FINISH-CURE™ 20 min. epoxy is an excellent, low odor substitute for polyester resins. It can be used for applying fiberglass cloth to wood or by itself to give wood a surface ready for primer and paint. FINISH-CURE™ can be sanded the easiest of all our epoxies and is excellent for the sheeting of foam core wings. Allow 8 hours for full curing. For best results, FINISH-CURE™ should be heated to a temperature above 85 degrees F or applying light weight fiberglass, lay cloth on balsa first, then brush on FINISH-CURE™. When fully saturated, go over the surface with a heat gun, and then squeegee off excess epoxy with a playing card from an old deck. Heat and remove excess several times for a lightweight finish. If room temperature is below 70 degrees F use a heat gun on the surface several times for the next 2 hours. When dry, lightly sand, then fill surface with a low weight spackling compound, scraping off excess with a playing card. Sand to a smooth finish ready for primer. For heavy weight fiberglass, apply the epoxy before and after laying down the cloth. FINISH-CURE™ is best mixed in a disposable cup.
