Product Review

TotalBoat Gelcoats create an exceptionally smooth, high-gloss finish on top of fiber-reinforced composites. These high-quality gelcoats contain a premium-grade ISO NPG polyester resin more durable than basic orthophthalic resins. As such, ISO NPG resins are preferred in many boat building, restoration, & repair projects for their greater strength, flexibility, water resistance, weather resistance, & chemical resistance.

TotalBoat Gelcoats are available without wax for use in layups, and with wax for finishing. Generally, 2% MEKP catalyst is best for most working conditions, but you can adjust the amount of catalyst to account for temperature differences. For cooler conditions, add up to 3% MEKP. For warmer conditions or longer working time, add 1% MEKP. At 77°F, pot life is 8-12 minutes. Cured gelcoat can be dewaxed, wet sanded, & buffed to a head-turning, high-gloss, protective finish.

Gelcoat without wax is typically used for the initial layer of a layup, but if you want to use it to achieve a tack-free cure, mix in a paraffin wax additive (sold separately) at a rate of 20 drops per ounce of gelcoat without wax (16 oz. of Gelcoat w/o Wax = 1/4 oz. of Wax Additive, 32 oz. of Gelcoat w/o Wax = ½-1 oz. of Wax Additive, and 1 gal. of Gelcoat w/o Wax = 2-4 oz. of Wax Additive).

TotalBoat Gelcoats can also be tinted to achieve a desired color. For neutral gelcoat, add 10% polyester resin or gelcoat colorant (12% for yellow, red, purple, light green, & orange). White gelcoat can be tinted using up to 1% gelcoat colorant. Always mix the colorant thoroughly into the gelcoat before adding the MEKP catalyst.

If thinning is needed, use styrene, not acetone. If applying to a mold, use a mold release agent first. Compare to West Marine Gelcoat and Evercoat® Gel-Kote. TotalBoat Gelcoat provides an exceptionally smooth finish and is a better value. All TotalBoat products are developed by boaters for boaters. We know what works and what doesn't. 100% made in the USA.
