Finish-Cure 20 min. constitutes a great low odor substitute for polyester resins and can be used to laminate fiberglass cloth over a wooden substrate or indeed be applied on it’s own to form a finish coat that can accept further primer and finish coats. Finish-Cure is the easiest of all the epoxies to sand and is ideal for the sheeting of foam core wings. For very well results, Finish-Cure should be heated to a temperature above 29˚C (85 ˚F) for applying lightweight fiberglass. Lay cloth on balsa first, then brush on Finish-Cure, when fullysaturated, go over the surface with a heat gun and then squeegee off excess epoxy with a stiff piece of card (a playing card from an old deck does the job well). Heat and remove excess several times for a lightweight finish. If room temperature is below 21˚C (70 ˚ 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, scrapping off excess with some 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 takes 8 hours to fully cure.
