Polyester 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.
| Slow Gel Time | Medium Gel Time | Fast Gel Time |
| 20 minutes or more | 15-20 minutes | 10 minutes |
| 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 |
