Clear Coat My Bass Boat

how to apply gelcoatTypically the clear coat on a bass boat is meant to protect the metalflake. You can choose a clear paint or clear gelcoat.

Clear gelcoat is typically what bass boats use at the factory for UV protection over metalflake but gelcoat isn’t as easy to use as paint. Gelcoat typically covers 48 sq feet applied at 18 mils thick per gallon.

The paints available in clear for spray application are the Supermarine Mono Epoxy, Two Part Epoxy, and Ironside Urethane. Paints typically cover 200-400 sq feet per gallon.

So paint vs. gelcoat, the thicker the coating the longer it takes for the sun to burn through. Time in the sun/elements is what will determine how long the clear coat lasts.

Use each product link for more information on price, application and  coverage (tabs under picture for specs/how to use).

Boat Blister Repair

Just because a blister or two develops on your boat it is not a serious issue and only a small number of boats develop a big problem with blisters.

Needed materials: Acetone, sanding block, Hawk Filler, acid safe disposable brushes

HawkFillerQuartCansMake sure blisters are drained and grind blister deep enough to remove damaged material beneath the gelcoat. Increase area as needed until all laminate around is sound. Clean area and allow to dry.

Hawk Filler goes on like putty to fill, patch, seal or rebuild aluminum, wood, concrete, fiberglass and steel. Hawk Filler can be drilled, tapped, or machined.

Mixing
Mix on a non-porous surface. Do not mix on cardboard, paper-based and/or porous surface. Wear tight-fitting rubber gloves. Using equal parts of Part A and Part B, mix thoroughly to even uniform color. Mix using a putty knife, trowel or spatula. Apply immediately after mixing.

Application
Apply using a putty knife, spatula or trowel. Spread smoothly on the surface in a 1/8″ – 1/4″ layer using heavy hand pressure to displace air bubbles/voids. If applying multiple coats, begin spreading away from the previously applied film so as not to trap air bubbles or leave an uncoated surface area. When using as a patch or grout, force material into hole or joint and smooth to the thickness needed.

CLEAN-UP
Wear chemical resistant gloves. Mix leftover Part A and Part B, allow curing before disposing. Scrape up spilled material with a putty knife or cover material with an absorbent material and sweep into a container for disposal. For product already mixed, use acetone.

After repairs paint with Sea Hawk bottom paint or if redoing the hull apply Tuff Stuff primer, followed by bottom paint.

If the blister has damaged the fiberglass that will need to be repaired with fiberglass cloth cut to match damaged area.

Choosing Anodes: Zinc or Aluminum

The main water types: salt, fresh and brackish call for different protection needs for your boat. Zinc and aluminum anodes protect in salt and brackish waters and never mix zinc and aluminum on the same vessel.

Zinc= Salt Water only

Aluminum= Salt or Brackish Water

Zinc and aluminum sacrificial anodes are for use on hulls, propeller shafts, rudders, trim tabs, outboard engines, stern drives and in the cooling system of most inboard engines to protect metal parts from galvanic corrosion. Check your manual for recommended size needed and  check them on a regular basis as environmental conditions can accelerate deterioration.
