Anti-fouling paint is a type of underwater hull paint, also known as bottom paint. These specialized coatings are designed for the exterior of the hull of a ship or boat, and combat the growth, as wells as, the detachment of underwater organisms, such as seaweed, algae and barnacles. These aquatic life forms bind to the hull and impact a vessel’s performance and longevity.
Anti-fouling paints are often applied as one component of a multi-layering process which can have other benefits in addition to their antifouling properties, such as acting as a barrier against corrosion on metal hulls that will degrade and weaken the metal, or to improve the flow of water past the hull of a boat or yacht.
Boaters recognized early on it is important to keep the bottom of their craft free of barnacles due to loss of speed and performance. The key is knowing when to pull your boat out of the water for a new bottom paint application. Ablative paints are typically reapplied every 1–3 years. One way to ensure you reapply your ablative antifouling paint when it’s needed is by adding a signal coat or flag coat.
To apply a signal/flag coat, when you are getting multiple coats of ablative bottom paint applied to your hull, make the first coat a different color. For example, if the bottom is going to be painted blue, make the first coat red. When the blue paint wears off and you see the red flag coat, it is time to repaint.

Inflatable boats have become very popular due to their flexibility and variety of uses. If your inflatable-bottom dinghy stays in the water for long periods of time and you have decided to apply antifouling paint you have a few options. You’ll want to apply a water based ablative antifouling such as Monterey by Sea Hawk, one quart is enough for two coats on an 8-10′ boat. Avoid a copper based paint on aluminum. Before application clean the area with a maroon Scotchbrite pad for good adhesion. These paints tend to be flexible and adhere well to PVC and Hypalon but since they are ablative they can easily rub off so be careful when storing your dinghy on deck or deflating it for longer storage to protect surrounding areas from paint.

Webbing Solution is a clear liquid added to gelcoat to obtain spatter or cobweb effects. It is mixed with a gelcoat of one color, and sprayed onto a contrasting colored surface.
Decorative effects produced by the webbing mixture will vary, and relate directly to techniques or gun adjustments. A fine hairline spider web pattern results from plenty of air and scanty material flow. Coarse and splotchy patterns are created by fuller material flow and decreased air volume. While our webbing solution is only tested with gelcoat, customers do use with paint achieving similar results.
The manufacturer suggests on the initial coat you add the wax and while gelcoat is still tacky, before it comes to a full air cure, you apply the contrast color of webbing (which should have the wax added too).
If you are applying webbing over fully cured gelcoat, sand with 150 grip, clean with acetone and then apply the webbing.
Mix 2 parts gelcoat to 1 part webbing. Mix proper amount MEK-P for the amount of gelcoat. Shoot at 10 to 12 PSI.
Add to colored gelcoat to obtain desired webbing effect. Test in an inconspicuous area to determine satisfactory results
SURFACE PREPARATION COATINGS COMPATIBILITY & ADHESION TESTS (ABOVE WATER ONLY)
Test One: Cross Hatch Adhesion (See diagram above)
Select test area(s) on the surface to be painted. Thoroughly clean, de-wax and degrease this area.
With a sharp blade, cut 6 lines vertically and 6 lines horizontally to give a box of 25 squares. The cuts must be deep enough to reach the substrate. On thick fairing systems this test may have to be done to several different layers.
Apply 3M #610, #895 or #898 3M Scotch Brand Filament Tape (or similar type of packaging tape) over the scribed area, making certain that the tape is tightly adhered to the test surface. Do not use masking tape.
With an abrupt yank, pull the tape back parallel to the surface. Pulling the tape straight up will give no test at all.
Examine the test surface. If any square of old coating in the scribed area is removed, the adhesion has failed. All the failed layers must be removed.
Test Two: Solvent Resistance
Saturate a cotton ball or small wad of cloth with one of the Awlgrip Topcoat or Primer Reducers (T0003 or T0006).
Tape the reducer-saturated ball to the scribed area surface for 30 minutes.
After 30 minutes remove the cotton ball. If the reducer has dissolved or severely softened the old coating, the coating is incompatible and must be removed. If the scribed area has remained intact, allow a 15 minute recovery period and repeat all steps in Test One again.
If any square areas are removed, all the failed layers must be removed.
Test Three: Coating Compatibility If the old coating is still intact after Tests One and Two, perform Test Three.
Lightly sand a small test area with 220 grit paper. Clean the sanded areas thoroughly with Awlgrip Wipe-Down Solvent (NA/AP: Awlprep T0008 ; EU: Surface Cleaner T0340) and using clean cloths.
Paint a small patch of the surface with Awlgrip Topcoat. Do not use masking tape on the edges of the test application as the paint edges created by the tape will ‘print through’ and be visible in the finish.
How long will it take to receive my order via UPS Ground shipping? The time to ship can be seen on most product pages and may vary by product. Most orders placed before 2:00 EST. Monday-Friday are shipped the same day with a few exceptions that will be noted on product page. Gelcoat/Resin materials along with any specialty colors typically ship in 2-4 business days. After the product leaves the warehouse, standard UPS shipping times apply. The map below shows estimated shipping times for items shipped via UPS Ground from our main warehouse In Florida, to destinations in the US. Please note that your order may ship from a manufacturer, or another warehouse resulting in less or more time stated in the map.

Do you have overnight shipping? This is not typically offered since the cost is about 3-4 times that of regular ground shipping and most of our items are considered hazardous material and travel via ground only.
If you are looking to remove some unwanted scratches on your boat or to bring back shine into your gelcoat, Aqua Buff is for you!
Aqua Buff is a polishing compound that we offer it in two variations: Aqua Buff 1000-W and Aqua Buff 2000. It is mainly used as a way to remove heavy oxidation, sanding scratches, and swirl marks from gelcoat. There are no oils or polymers in Aqua Buff, so the surface you see is the true surface.
The Aqua Buff 1000-W is used for deep scratches and heavy oxidation. It has a blue-green color which is why is not recommended for white hulls. Use Aqua Buff 1000-F on white surfaces. Aqua Buff 1000-W removes 320 – 600 grit scratches.
Aqua Buff 2000 is used for finer scratches, swirl marks, and light oxidation. Use it to remove 1000 grit scratches and higher. Cleans and removes scratches from Fiber-Reinforced-Plastic parts, metals, and painted surfaces. It is strong enough for most uses and provides a shiny finish.
Apply a small portion of Aqua–Buff 1000-W or 2000 on the surface using a brush or microfiber cloth (stick to a small area)
Use a spray bottle to mist the surface with water. Only use about a coin-size amount of compound per square foot.
