How to gelcoat a jet ski

If your jet ski or waverunner hull is made of fiberglass then gelcoat can be an excellent restoration option. Gel coating a jet ski is a great way to keep it looking new and protect the surface from scratches and dings. It’s also a relatively easy process that most people can do in a few hours. In this blog post, we’ll walk you through the steps of how to gelcoat a jet ski. We’ll also provide some tips on how to make the process go as smoothly as possible.

What is gelcoat and what does it do

Gelcoat is a type of resin that is used as a protective coating on many boats, jet skis, and wave runners. It is applied to the hull of the vessel in order to provide a shiny, smooth finish. In addition to its aesthetic benefits, gelcoat also helps to protect the hull from UV damage, scratches, and other types of wear and tear. In some cases, gelcoat can even help to repair minor damage to the hull. As a result, gelcoat is an essential part of any boat or jet ski owner’s arsenal. While gelcoat can help extend the life of your jet ski or wave runner, it is not indestructible. Over time, it can become dulled or scratched, and it may eventually need to be replaced.

How to clean and prep the jet ski surface before you start

To clean the jet ski, you’ll need a mild soap, a soft cloth, and a jet ski brush. Start by mixing the soap and warm water in a bucket. Then Wet the jet ski with the soapy water and use the brush to scrub away any dirt or grime. Rinse the jet ski off with clean water and dry it with a soft cloth. For tough grease and dirt spots you can use a degreaser. This will remove any dirt, grime or grease that could prevent the paint from adhering properly.

Finally, inspect the jet ski for any cracks, chips or other damage. If you notice any of these, make sure to get them repaired before applying gelcoat. Use a fine-grit sandpaper to smooth out any rough spots. Gel coat repair kits, scratch patch kits, gel coat paste, fiberglass repair kits come with everything you need for small repairs.

Applying the gelcoat to your jet ski, wave runner

Applying gelcoat to a jet ski is a great way to protect your investment. Gelcoat is a clear or colored coating that is applied to the surface of a jet ski to protect it from the elements. It is also used to give the jet ski a high gloss finish. Gelcoat is available in both spray and brush-on versions. The brush-on version is generally easier to apply, but the spray version will give you a more even coverage. When applying gelcoat, be sure to follow the manufacturer’s instructions carefully. In general, you will want to apply several thin coats rather than one thick coat. Be sure to allow each coat to dry completely before applying the next one. Once the gelcoat has been applied, you will need to buff it out to achieve a high gloss finish. Once the final coat of gelcoat has been applied, the jet ski should be allowed to cure for 24 hours before being launched.

It’s important to choose the right gelcoat. There are dozens of different formulations on the market, so it’s important to do your homework and consult your owner’s manual. Once you’ve selected the right gelcoat, the next step is to apply it correctly. One common mistake is to apply too much gelcoat, which can lead to runs and sagging. It’s important to apply a thin, even coat and then allow it to cure properly before sanding or buffing.

With these tips in mind, your gelcoat project should be easier. Just remember to take your time and follow all instructions carefully, and you’ll soon be enjoying your jet ski on the open water. If you have any questions about selecting the right gel coat for your watercraft, please call the Bottom Paint Store customer support team 888.505.2313.

“Highly rated product”.- Scott H

“Great tried something last year and came back to PropGlide this year.- Carl R.


PropGlide is an excellent protective coating for my propellers.- Louis S.


Easy to use. Too soon to comment on how it works. My boat is not yet in the water.-
Goes on as described, the prep is the hard part. We will see how it works when I drop it in the water in the new few weeks. Expect it to work as advertised. I ended up with the medium kit and it was way too much for me. 2 – 3 bladed props about 12 inch blades plus the shafts. Better to have too much than too little I guess but next time I will order the small instead of medium.”

“I have used it before and (it) works great.”

“Easier to apply than Propspeed. Almost twice as long between the primer and the top coat.”


“It’s always nice to be able to order and receive in a timely fashion what you need for your boat running gear.”- Curtis S.


“Easy to apply, looks good.”- Greg D.

“Just applied it. We will see how it works during the coming season”.- Shawn H.

“Works as advertised”.- Raymond R.

The following testimonial was provided outside of Verified Reviews.

“We applied PropGlide to the propellers and rudders on our 42′ power catamaran in March 2016. We have found excellent results so far with very little growth appearing on the running gear. We have been able to maintain great boat speed, excellent economy and no vibrations unlike previous years with using other products. Our Applicator has even commentated how much easier PropGlide is to apply compared to its competitors.” – Mick M.

Pettit Vivid Reviews

Pettit Vivid Antifouling

A very effective bottom paint for the Great Lakes. – David B.

Compromise between more ablative and full hard paint for your hull. – Bert R.

I haven’t used the paint yet but I expect it will live up to its reputation. – Tom Z.

The best paint.

Pettit Trinidad Pro Reviews

Trinidad Pro

We first used Pettit Trinidad Pro on my sail boat in 2014. Now in 2021 a full 7 years later we have to repaint. Probably should have repainted last year but regardless of 7 years or only 6 years of effective coverage its amazing. Virtually no bottom growth for 6 years – WOW. This would be my permanent choice for bottom paint if Pettit were not finally giving up the fight. – Michael H

The delivery was fast but the gallon can was badly damaged due to the weight of the product inside. Nothing wrong with the contents and the package did have a red warning label Do Not Drop. Can’t blame the store, just the shipper. – Robert K

Used before it’s great.

Pettit Black Widow Bottom Paint Review


Pettit Black Widow Racing Antifouling, Black

Went on thin but easily. Definitely needs two coats as the sanding/buffing to bring out the best in the product was worn through on edges/thin spots. Seems very slick….first time trying this one.

I will know more later in the summer and beyond. I am hopeful that it is as good it sounds. I tried a roll and tip method for applying the two coats of paint, and it sets up too quickly for that, so I think it would be applied better by either roller or brush alone.

Pettit HRT Paint Reviews

Unepoxy HRT, By Pettit

I love this paint. This is my fifth year, and only have had to do some touch up on the boat bottom. Excellent. – Fran Z.

Love this product have used it many times before on several cruisers and fast boats always greatly impressed with the outcome.

The Many Uses of Polyurethane Paint and Coatings

Polyurethane paint, also referred to as PU paint or PU coating, is a durable, highly-resistant coating used in industrial and architectural coating systems. It is popular in the marine industry and is used for numerous applications including coatings, rigid and flexible foams, and varnishes. It is also used in steelwork, concrete, wood, and other substrates.

Polyurethane is a reaction polymer, a combination of a polyol resin and an isocyanate hardener or curing agent. Essentially, a polyurethane coating is a liquid plastic which dries to form a paint-like film on an underlying substance or layer. Polyurethane paint provides durability, resistance to chemicals, water, abrasion, and temperature, as well as an attractive glossy finish. The most common application of polyurethane is as a solid foam, accounting for approximately 60% of all polyurethane produced.

Marine Polyurethane Clear Coat

Polyurethane can be used to protect a boats paint and to keep the finish on wooden marine vessels visually appealing and more durable. You can apply polyurethane over any type of paint if it is clean and prepared properly. Polyurethane coatings can be applied to exposed wooden surfaces to create a glossy finish that serves to repel water, resist corrosion, and protect from scratches, stains, and UV damage.

Blue Water Marine Mega Gloss Polyurethane

Mega Gloss by Blue Water Marine is a single component topside polyurethane enamel that can be used on fiberglass, wood, aluminum, and steel. It provides a hard protective coating for super high gloss, color retention, and long durability. Mega Gloss is fast drying which when brushed or rolled, it can also be sprayed, and offers a smooth finish, is resistant to tough chemicals, cleaning solutions and ultraviolet light.

Polyurethane Foam Uses

Sea Hawk Polyurethane Foam

Sea Hawk polyurethane foam is urethane foam that provides excellent flotation, soundproofing or insulation. Mixed 1:1 and easy to install in hard-to-reach places. Poly-U-Foam bonds to wood, metal, and fiberglass. It foams wherever it is poured and is impervious to solvents and gasoline. A 2-quart kit will yield 2.5 cubic feet of space. Available in 2lb density. It is advised not to use below 70°F.

Liquid Urethane Foam Kit

Liquid urethane foam is a closed cell foam that comes in varied sizes, most commonly 2LB, 4LB, 8LB and 16LB densities. This two-part liquid, expanding rigid urethane foam is a closed cell, pourable foam, which will resist the absorption of water. It is the ideal boat foam for structural applications as it is resistant to water penetration and can be used for flotation, insulation, casting, carving, sculpting, sign making and areas where an extremely durable (you can penetrate with a fingernail) while it cannot be dented by hand, making it ideal for support.

Pettit Easypoxy/ EZ-Poxy

Pettit EZ-Poxy is an advanced one-part polyurethane topside and deck enamel. It’s a high gloss finish flows well when applied with a brush. It is a modern one-part polyurethane topside and deck enamel. It It’s use of silicone provides a brilliant shine and easy brush-ability. Its advanced ultraviolet filters enhance the superior gloss retention and durability of polyurethane. The result is a topside finish that is exceptionally easy to apply, producing a lasting gelcoat-like brilliance with a minimum of effort. It is more economical, requires less effort, and is more forgiving than the competition.

Easypoxy’s innovative ultraviolet filters improve gloss retention and enhance the polyurethane’s durability. This results in an end product that is simple to apply and easily creates an enduring shine and superior gloss retention, similar to that of polished gelcoat. Pettit Easypoxy is available in numerous colors.

Interlux Spray Reducing Solvent

Interlux’s Reducing Solvent 2316N is for use in specific two-part polyurethane and epoxy products. It is an amazingly effective, fast evaporating solvent. Safe for aluminum outdrives. Refer to the specific product directions for the amount to be used.

Interlux Pre-Kote

Pre-Kote® is a unique V.O.C. compliant, single package, undercoater or primer for use with Brightside® Polyurethane, Yacht Enamels, or anyone-part topside finish. Microspheres give Pre-Kote® superior build and hide while improving flow and sandability. Use anywhere above the true waterline where a coating is needed to provide a smooth, fair surface for overcoating with a topside enamel.

Interlux Goldspar Satin Varnish

Designed for interior wood surfaces, Interlux Goldspar Satin Varnish is a modified polyurethane low luster varnish. It produces a rich satin sheen finish that resists scratches and stains and applies easily enough to yield truly professional results by either brush or spray. It’s low luster finish makes it ideal for cabin soles, cabinets, counters, tables, as well as home interior finishes.

Urethane Paint

Urethane paint was created in the mid-1960s, utilizing newly developed plastics technology, and designed to be superior to enamel paint in terms of durability by mixing pigment with polyurethanes, which act as the binder to hold the pigment molecules together. Semi-gloss urethane paints have been developed, but all urethane paint will have some degree of glossiness, because the same properties that make it resilient also make it reflect light. It has become a staple in the marine and automotive industry because of its durability.

AwlGrip Topcoat

AwlGrip Topcoat is a polyester based high gloss polyurethane topcoat giving long lasting gloss and color retention. It can only be applied above the waterline of your boat by either a brush, roller, or spray. You should apply Awlgrip Topcoat in two coats of 1.5 to 2.5 mils WFT each and allow 16 hours between each coat. Sanding between coats with 280 to 400 grit paper will provide a smoother finish.

Interlux Perfection Plus

Sea Hawk Aluma Hawk Paint Reviews

Seahawk aluminum boat paint is perfect. No primer required. I’ve used this paint for two years with excellent results. – William E.

Great product. – Kody L.


Very impress with the paint covering, 1 1/2 half gallon for my 20 feet pontoon.- Cristian V.

Adhesion seems better than most paints even when not fully cured. Liking what I see so far. – Mark L.

Great paint and easy to use. Took a little bit longer to dry than expected, but that was mostly a humidity issue on my end. Looks great and it will buy it again if I need some more for anything.- Eddie C.

Haven’t used it yet but I ordered it because of its good reviews on YouTube.- Jesse H.
Great product. Bruce D.

Excellent product for my Jon Boat- Dennis E.

Looks great! Sam B.

I learned several things about this paint; 1. Make sure you apply it soon after you receive it. If it’s going to sit for a couple of weeks, you will need to stir it very well to break up chunks in the bottom of the can. 2. Two quarts are not enough to paint the bottom hull of a 14-foot aluminum Jon boat. It will take at least 3 quarts for 1 coat. 3. Wear gloves. If you get this on your hands, it will take longer to get off than regular paints. 4. It takes a week to cure. It says so on the can and I can see that. Even though the paint appears dry after a few hours, it’s still tacky. So, you will need to have some patience. Seriously, this is not like painting other objects like wood. Read all the directions and act accordingly. Keep in mind that this is for boats that will routinely be out of the water. It has no anti-fouling properties, and that’s OK if you’re not going to leave it in the water. Personally, I live in a desert area of Arizona, so not an issue for me. – Kevin P.


The best product for aluminum boats.- Robert D.

Purchased an older small used pontoon for our no motor lake. The bottom crud was like cement and I eventually used a sand blaster wand attachment to my power washer to clean of this crud (unreal). Chose Aluma Hawk paint for the sand blasted pontoons and it worked great. This paint needs to be used in a WELL ventilated area!!! I was outdoors painting with a roller on a calm morning and decided to wait till the wind picked up to finish. Tough durable and easy to use. The green makes it look like its from the military surplus! Love it. Certainly the fish will be confused. LOL.- Keith B.

Smooth application.- Brad H.

Very good paint. – Chris T.

I used a roller went on smooth. – Roger C.

The paint match was pretty close to what the previous owner said he put it on the boat… I only did the transom and some touch up on the sides. Good quality paint for an aluminum boat.- Rich H.


I purchased the Aluma Hawk 7031 lite gray – 1 gallon, which gave me 2 coats on the bottom & 1 coat inside. The factory didn’t recommend spraying the paint, so i rolled it & brushed it on. The paint dries quickly, so you have to work fast to maintain a wet edge. I did small sections at a time to make sure I got even coverage. – Russell S.


Haven’t used it yet. – Joe S.


Love this paint. I painted my jon boat years ago with this stuff. It holds up, doesn’t fall off or fade. Added pods to my boat and had to get another quart. The color matched really well.- Steve K.


Great paint, just needs to be shaken before shipping.- Greg M.


This paint if fantastic! It adhered to my boat very well and it only needed one coat to cover evenly. – Arnold B.


Met all my expectations for painting exterior of houseboat. I strongly recommend!- Marsha M.


Best I ever used on alum!!!!!!!!!!!!!!!!!!!! – Herman B.


The Value is in the Lasting Performance so I shall see. Putting it on, one NEEDS to KNOW what they are dealing with BEFOREHAND as far as Application, in knowing this project should come out perfect. Price of this product should be determined by it’s worthiness over time. Clean Up be SURE to use right Measures and Tools.- Jerry H.
Works good, dries well, one quart did a first and second coat on our jonboat.- Lindsey M.


Anticipating the paint will be great- Paul M.


Great products. – D. Mendez


Great product. Best bottom paint I have used yet. Good ventilation required. -Jon B.
Awesome- Todd Z.


Paint was as advertised. Very pleased with product. Would highly recommend.- Jerry R.
Easy to apply and dried quick, didn’t even really need a second coat but put one on anyway. -Sarah L.


Applying the product now and appears to be coating and covering as described. The painting (job) isn’t complete yet so I can’t comment on life longevity or wearing but satisfied so far. – Jason K.


This appears to be a good quality product but is not real user friendly for DIY due to the fumes and the fact that MEK is needed for clean up. – Douglas L.


So far pretty good, it’s been about six months now since application. I recommend reading the directions very well, it tells you exactly how to thin and apply with the exception of what type of roller to use, I used a 1/4 nap roller but seemed to go on pretty thick. I had to thin it a bit more than what it said in order make it a bit easier, it recommends rolling as best method but I believe spraying would be better. A 16 foot long 5 foot wide vhull took about a gallon and a half to paint but I believe it is because it was going on pretty thick, to spray it says can be thinned 50% but for roller or brush only 10% which seemed to thick and not much coverage, either way you have to move pretty quick because it will flash pretty fast. It dried to touch pretty quick but due to the thickness from rolling it seemed to take forever to fully dry and or cure during which time it was still pretty soft and easily scratched off. After being left to sit and fully cure/harden I will say the stuff seems pretty hard and tough as nails. I used the sand color and if an when the time comes to paint the boat again I would use it again only spray it . I initially bought a gallon and a quart but soon realized it was going to be enough so I bought another gallon and still have about half of it left, I applied two coats to the entire boat both inside and out.- David P.


Great- Todd Z.


The paint went on as expected will have to wait and see how it holds up.- Howard B.

Sea Hawk Cukote Paint Reviews

I thought the value was great even though I haven’t used it yet due to my marina being backed up with haul outs so Ill probably get hauled out after hurricane season is over, plus it will be cooler then as well.- Michael W.

The quart I bought was surprisingly heavy but instructions were clear and it was easy to apply. Certainly recommend gloves and a disposable brush. – Peter S.

Boat had never been painted and I prepped and applied 2 coats below the waterline and 3 coats on the waterline . Held up for 2 years in coastal NC waters . Very little growth to remove . Pressure washer blew most of it off . I would call Sea Hawk Cukote a very good product. – D. Bordeaux

After more than 40 years experimenting with different bottom paints on many boats, I’d have to say Sea Hawk paints are the best (least fouling, longest-lasting) ablative paints I have found. – Stephen P.

Quick delivery good pricing. – Robert S.

I kept my sailboat on the Chesapeake in an area with warm brackish water very conducive to barnacle growth. Cukote worked better. – Robert P.

Excellent product. Alfred L.

IMO, this is the best bottom paint. Only requires one coat. – Gerald D.

It is on our boat now and we needed some touch up. – Carol S.

Great product to use on boat bottoms. – Jeffrey R.

Sea Hawk Tuff Stuff Reviews

Cleaned the surface, highly recommend a fan or 2 when using. Does have strong odor like any reducer or thinner. – Peter P.

A high quality epoxy paint. I will order it again. – Edward O.

Applied well, pretty happy so far! – Sam B.

Love it. Easy to work with and tough when cured ! Easy to wet sand also in prep for color coats ! – James W.

Very easy to use, just follow the directions. I have not put the boat in the water yet, but I don’t forsee any problems. – Sharon T.

The Sea Hawk Tuff Stuff was very easy to work with and the 1:1 ratio made mixing easy and error free. It went on easily and dried quickly so that I could apply 2 coats plus bottom paint In one day on a 46ft. Motor Yacht. The Sea Hawk Tropicoat was also easy to go on ( I recommend thinning as the paint is extremely heavy with copper). It dries quickly and have a hard service in 15 minutes. I am very happy with both products. – George M.

Great primer, the name says it all. – Eric H.

Very good product. – Nicholas C.

How Can Gelcoat Be Used to Repair Fiberglass Surfaces?

brushable gelcoat

Gelcoat is popular as a surface coating in the fabrication and repair of fiberglass-based products and can also be used to patch existing gel coat, fiberglass repairs, and new construction and repair projects. Gelcoat is extremely durable and provides a high-quality finish to visible surfaces making it a popular solution for damages to fiberglass surfaces such as covering up blemishes, patching small holes, filling cracks, and renewing surface shine. Gelcoat is often referred to as a one-stop solution for almost all types of damages on fiberglass surfaces such as, boats, jet skis, wave runners, swimming pools, hot tubs, showers and more.

Gelcoat for Swimming Pools

If you have a fiberglass pool then its surface is made of gelcoat, a liquid-colored resin that is applied to the pool shell. Gelcoat is the considered one of the most durable pool surfaces, typically lasting several decades, depending on maintenance, wear and tear, and the quality of the surface. Concrete pools need to be refinished about every ten years or so.

One of the more common areas of a fiberglass pool that needs to be refinished over time are the pool steps which can fade after exposure to pool chemicals, weather and UV rays. For more information please refer to our How to Gelcoat your Fiberglass Pool Steps article.

Gelcoat for Shower Stalls, Bathtubs, and Hot tubs

Cracks, holes, chips, and stains in showers and tubs made from fiberglass can be repaired with gelcoat. A common rule of thumb is if the hole is smaller than 1/2 inch, you should be able to make the repairs yourself; if it is a larger hole, then it may require the replacement of the surface or unit.

Fixing the damaged area requires applying two-part epoxy that hardens to the strength of the surrounding surface.

Gelcoat for a Fiberglass Deck

One of the most common ways to refinish a fiberglass deck is with a two-part polyurethane, as the results will provide a finish that will look as good as and should last at as long as the original gelcoat.

Re-gelcoating a Boat Fiberglass Hull

Regularly waxed gelcoat can last up to 15 years, depending on how well you take care of your boats hull and exposure to UV rays. If your hull is showing signs of damage such as cracking or is no longer retaining its gloss, and has chalky white powder on the surface, then it is time to re-gelcoat your hull. Dewaxer is perfect for dewaxing the hull and effectively cleaning up paint supplies.

Be Prepared for your Gelcoat Project

Using gelcoat can be an excellent solution for repairing and renewing fiberglass-based surfaces. Gelcoat is sometimes referred to as marine paint for fiberglass, however it is not a paint, so if you are unfamiliar with applying gelcoat, please see our numerous how to articles as it can be difficult to apply and achieve optimal results for first time users. You can also contact Bottom Paint Store’s technical team from 8:30-5:00pm EST Monday through Friday.

The Different Types of Pettit Paint

Pettit Marine Paint, was established back in 1923 and is a manufacturer of a variety of boat paint including marine coatings, antifouling boat bottom paint, varnish, and epoxies.

Hard Modified Epoxies – The active ingredient leaches out while the paint film stays mostly intact. Leaching Coppers lose performance as time goes by and must be repainted after dry storage.

Pettit Easypoxy is an advanced single-stage topside polyurethane and deck enamel. It has a superior high gloss finish and flows well when brush applied. Easypoxy’s innovative ultraviolet filters improve gloss retention and enhance polyurethane’s durability.

Captain’s Satin Sheen Varnish V-975 is widely esteemed for its reliability, multi-purpose application, fast-drying capability, and superior durability.

Ablatives – (Ultima and Hydrocoat Technology) Ablative polymers paints wear away with use exposing new biocides, both the biocides and the paint film disappear over time. Ablative Polymers can be used multi‐season and maintain a more steady performance throughout their useful life.

Pettit Black Widow Racing Antifouling is the slickest, fastest, ultra-smooth, burnishable racing finish available. Its powerful dual biocides provide multi-season protection in all waters. Black Widow is easily applied by roller, brush, or spray and is easily burnishable to a metallic “gun-metal” shine.

Hybrid – (Vivid Technology) Hybrid antifoulings offering hard paint that does not build up. Hybrid’s work by leaching out the biocides just as a Traditional Leaching Copper does, but once the biocides are gone, the paint film will break down exposing a new layer of biocide.

Trinidad HD, Multi-Season Hard Antifouling Paint provides excellent, long-lasting protection, even under the toughest antifouling conditions. Trinidad HD provides dependable in-water antifouling protection while meeting the 330 gram per liter VOC regulations.

Copper Free – Econea is a non-metal biocide that is extremely effective against hard-shelled fouling organisms including barnacles, hydroids, mussels, oysters, and tube worms.

Odyssey HD multi-season antifouling combines controlled polishing ablative technology with a high copper content to provide a paint film strong enough to handle the tough marine environment from coast to coast. Odyssey HD is compatible over most finishes, 50 state V.O.C. compliant, and will not build up over time leaving running surfaces smooth and clean.

White Copper -(Cuprous Thiocyanate)- requires 50% less copper content than the heavy, dark copper used in conventional antifouling paints. They are the only copper-based paints that are compatible with aluminum.

Low-Density Copper – replaces the core of traditional Cuprous Oxide with environmentally friendly materials found naturally in the ocean.

Irgarol – is used in many dual biocide products, Irgarol is an algicide designed for use in antifouling paints to prevent soft growth such as algae and grasses.

Water-Based (Hydrocoat Technology)- This formula uses water to replace the harsh solvents found in conventional antifouling paints. The product has an extremely low VOC content.

Clean Core Technology – An enhanced paint film that can reduce the amount of heavy metals released into our waters by up to 90%. These new additives have been specially formulated to provide a more “finetuned” and consistent release of the biocides from the paint film. This results in a more effective bottom paint that requires lower biocide levels to deliver full antifouling protection.

Pettit SR vs Pettit PRO

Pettit Ultima® SR-40 features an enhanced formula that utilizes an increased biocide load combined with PTFE to offer an outstanding multi-season control in all types of fouling. SR-40 employs a unique controlled erosion technology to minimize coating build-up and keep underwater surfaces smooth.

The Different Types of Boat Paint

In this article, we will briefly describe some of the different types of boat paint that can be used to repair, restore, protect, and make your boat looks its best.

Topside boat paint is a type of paint you apply above the waterline of a boat. This can include the sides of the hull, deck, as well as interior. Marine topside paints usually consist of one-part polyurethane, two-part polyurethane, and alkyd marine enamel. There are also buffable, two-part acrylic urethanes. Due to the sun’s rays, your boat is vulnerable to UV damage so coating your upper hull and deck with good topside paint can go a long way to protecting your boat.

Blue Water Marine Topside Paints are superior in quality, higher in value and typically, priced better than store brands


Aluminum boat paint can be used for many purposes including to camouflage, decorate, refurbish, or restore aluminum boat surfaces. Paint that is safe for aluminum and can be applied without a primer and can be used below or above the waterline.

Aluma Hawk Paint
Aluma Hawk is a fast drying, high-solids, corrosion-inhibiting coating designed for use on aluminum with no need for a primer.


Fiberglass coatings usually consist of gelcoat, gelcoat putties, resins, restoration solutions, repair kits, and tools/materials. Gel coats are often used to touch up or repair a boat’s finish. They have a much shorter shelf life and can be a lot more difficult to apply than paint so the manufacturer’s instructions must be carefully followed to ensure a successful result.

Gelcoat can be used to patch existing gel coat, fiberglass repairs, and new construction and projects.


Wood boat paint typically includes traditional types of oil-based finishes, as two-part paints tend to be less flexible. Because wood can flex and swell, especially along seams, expensive finishes will not last any longer than traditional stain or paint. Teak can be used to prevent fading on a boat’s wood finish. If left untreated, it will often fade which leads to the need to clean or treat the wood so it is not susceptible to rot, mildew, and discoloration.

Just Teak is a simple solution to clean, brighten & protect your teak.


Bottom boat paint is antifouling paint or coating designed to diminish weeds, barnacles, and other aquatic organisms that can attach below the waterline of a boat and cause damage. Bottom paint includes ablative bottom paint, hard boat bottom paint, aluminum safe bottom paint, primers for bottom paint, and boat bottom paint remover.

Biocop bottom paint uses the newest biocide technology which is safe for the environment.

How to repair a hole on the side of your boat

Repairing a hole on the side of your boat is possible by following this guide and using epoxy resins for wooden boats.

Begin by inspecting the hole for any cracks that extend away from the
hole and clearly mark the entire area that needs to be patched. You want to be sure to extend your mark out beyond the damaged area by a few inches.

Hawk Epoxy f2 Structural Adhesive Filler

Cut the marked area with a hand saw making sure the hole is beveled in order to allow layers of fiberglass to fill the hole. Measure the thickness of the hull substrate and multiply it by 10. This is the distance from the hole edges that the bevel needs to accommodate.

Use a power sander with a 50 grit sanding disc to bevel from the whole edge out to your mark. Fiberglass layers are going to be placed on the outside of the hull. Use a flat backing on the inside of the hole to keep the wet fiberglass cloth from caving into the hole.

Next cut six pieces of fiberglass bi-axle cloth with the first piece being the size and shape of the outer edge of the bevel. The final sixth piece being the size of the hole itself. Remember it is important to use fiberglass bi-axle cloth for hole repairs.

Wet out the beveled area of the hole with a mixed epoxy. Lay the cut fiberglass bi-axle cloth on a piece of plastic going from large to small pieces. Make sure to wet each piece as you place them on top of the next piece. When wetted out properly the bi-axle cloth will become transparent. Put the wet out pile of fiberglass bi-axle cloth into a piece of peel ply, with the small pieces down. Next, mix the Hawk epoxy f2 filler and hawk epoxy resin catalyst until you reach a soft butter consistency.  

Hawk Epoxy Resin Catalyst

Brush this mixture onto the beveled area of the hull and be sure to center your filler. Wipe off any extra leftover epoxy from the hull, squeegeeing out the air pockets and wiping with a clean cloth that has been dampened with solvent. This will be a lot easier than sanding it off later. Allow the patch to cure for the recommended cure time (overnight is typically sufficient) per the instructions on the hawk epoxy resin can label.

Once it has cured, remove the repair area backing on the inside of the hull. The repair area on the inside of the hull can be left untreated if it will not be exposed to sunlight. Remove blush with soap and water. Next sand off any rough areas on the outside of the hull with 80 grit sandpaper and then sand with 100 grit sandpaper the entire repair area so it is completely smooth (this may require a disc sander if it’s too difficult to sand by hand). You can dust off the area a clean cloth, air gun or brush it off with a clean brush.

F5 Light Density Fairing Filler

Prepare a batch of Hawk epoxy resin and catalyst. Apply coats to the repair area with wet epoxy, with the remainder of the Hawk epoxy resin mixed in the Hawk epoxy f5. Lightly mix filler until density is a medium thickness
with no sag consistency.

Next, spread the mixture onto the repair area and squeegee the area until as smooth as possible. Allow the area to cure until you can push the corner of the squeegee into the surface and only a slight indentation remains. Repeat the process with Hawk epoxy mixed resin and f5 light density filler, adding another coat of this mixture onto the repair area. Let this cure for 10 to 12 hours.

Remove the blush with soap and water and sand the repair area with a smooth 80 grit sandpaper.

To add color, mix another small batch of Hawk epoxy and introduce the liquid dispersion as this will seal and fill any low areas. Now that you have a strong and
sturdy hull side you are ready for paint!

What Is Zinc Chromate Used For?

Zinc chromate is used for a wide range of applications. It is an odorless chemical compound primarily used as an industrial paint coating. The compound is a beneficial coating because it is an anti-corrosive and an anti-rust primer. It is primarily used to coat aluminum and iron materials. Developed by the Ford Motor Company during the 1920s, it was historically used on aircraft by the US military during the 1930s and 1940s. It is also widely used as a paint coating for the aerospace and automotive industries, as well as, a coating for boats, due to its ability to destroy organic growth on the surface and to protect aluminum from corrosion.

Zinc chromate is on the hazardous substance list and regulated by OSHA because studies have shown that not only is zinc chromate highly toxic, but it is also a carcinogen. It has been cited by ACGIH, NIOSH, DEP, IARC, HHAG, and EPA.

What is zinc chromate used for

Duralux ZinKromate is a high-quality synthetic primer for use in light to moderate marine exposures. It is lead and chromate free so it is safe to use; however, it offers all of the performance and quality characteristics of zinc chromate without the health and application hazards. It has good chemical and corrosion resistance, dries fast, and allows single finish coat coverage when using a like-colored topcoat. ZinKromate performance primer adheres very well to steel, iron, aluminum, or partially rusted galvanized surfaces.

S-76 Strontium Chromate Tack Coat Primer is for use on properly prepared steel, aluminum, or galvanized steel. S-76 is an anti-corrosive strontium chromate-based primer that is specifically designed for underwater metal surfaces including hulls, running gear, and the lower units of outboards and I/O’s. It provides an excellent barrier to reduce the pitting of the metal from galvanic corrosion.

S-76 Strontium Chromate Tack Coat Primer

Stromate Chromate tack coat primer may be used on bare aluminum in conjunction with Tuff Stuff High Build Epoxy to form a barrier for the application of copper-based antifoulants.
