FINISHING RESIN also works great for fuel-proofing engine compartments. Because of its thin viscosity, FINISHING RESIN is not recommended for molding fiberglass parts - use Sig Polyester Glass Resin instead. FINISHING RESIN must be chemically activated with "hardener" in order to cure. It absolutely will not dry unless hardener is added! Because the amount of hardener required can vary slightly depending on the curing time desired, we feel it is a better value to buy the resin and hardener separately. Sig Resin Hardener is listed in this menu.
NOTE: Finishing resin has a limited shelf life of 2 to 3 years, and should be used promptly. Please do not order more than you can use within that time. Store in a cool place, excessive heat will shorten shelf life. 

Finishing Resin is thinner than normal epoxy, it spreads and wets out superbly. It is used to fill the weave on light fiberglass finishes or as the final coat on heavier cloth. Also works great for fuel-proofing engine compartments. Brush-on surfacing resin for sealing balsa and creating a glass-smooth durable base for epoxy or enamel paint.

A brush-on surfacing resin for sealing balsa and creating a glass-smooth durable base for epoxy or enamel paint.

It has a thinner viscosity than regular Sig Glass Resin for maximum penetration into the wood.

• Simply brush Finishing Resin onto the bare balsa.
• Before the resin cures, squeegee off any excess resin with a plastic epoxy spreader or ordinary stiff playing card.
• Wipe off any runs or drips with a paper towel.
