This is a general purpose polyester resin for applying fiberglass cloth or for sealing balsa wood. Glass Resin is a perfect match with Sig Glass Cloth for molding your own cowlings, wheel pants, fuselage shells, boat hulls, and many other items.

Glass Resin must be chemically activated with "hardener" in order to cure. It absolutely will not cure 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 for you to buy the resin and hardener separately. Sig Resin Hardener is listed below on this menu and must be purchased separately.
