TotalBoat Gel Coat creates a durable, super-smooth, high-gloss coating on boat hulls, RVs, composite parts, and even repairs to fiberglass showers and tubs, pools and more. This high-quality boat gel coat contains a premium-grade ISO NPG polyester resin more durable than orthophthalic resins, and is preferred in boat building and as a gelcoat repair kit for boats due to greater strength, flexibility & protection against damage from water, weather, and chemicals. Gelcoats are available without wax for use in layups, and with wax for finishing. 2% MEKP catalyst is best, but in cooler conditions, add up to 3% MEKP. In warmer conditions or for added working time, add 1% MEKP. Cured gelcoat can be dewaxed, wet sanded & buffed to a high-gloss, protective finish. Gelcoat without wax is used for the initial layer of a layup, but for 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 = -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 and orange). For white gel coat, use up to 1% gelcoat coloring agent. Always mix colorant into gelcoat before adding MEKP. If thinning, use styrene. If applying inside a layup as the first layer, use a release agent first. If applying over TotalBoat TotalFair epoxy fairing compound, apply TotalBoat 2-Part Epoxy Primer or TotalProtect before applying Gelcoat boat paint.
