Finishing resin for building and repairs

Because it contains wax, TotalBoat Polyester Finishing Resin is typically used for one-coat glasswork or as a final, tack-free, sealer coat over tacky polyester laminating resin coats. It cures clear and hard to resist scratches and staining. Wet sand and buff to a glossy finish, or sand, paint, or gelcoat over. Also known as marine fiberglass resin, polyester finishing resin can also be used for any layer in a laminate that needs to be sanded.

Gel time depends on amount of hardener admixed

The following table indicates approximate gel times @ 70°F. Adjust the hardener level to slow down or speed up gel time. Cooler temperatures may require a higher percentage of hardener than warmer temperature conditions.

1 teaspoon of hardener per quart of laminating resin 2 teaspoons of hardener per quart of laminating resin 3 teaspoons of hardener per quart of laminating resin
