BSI Finish-Cure 20min Epoxy 128g (4.5oz)
Finish-Cure 20 min. epoxy is an excellent, low odour substitute for polyester resins. It can be used for applying fibreglass cloth to wood or by itself to give wood a surface ready for primer and paint. Finish-Cure can be sanded the most easily of all the BSI 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 30 degrees C (or 85 degrees F) for applying light weight fibreglass, 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 light weight finish. If room temperature is below 21 degrees C (70 degrees F) use a heat gun on the surface several times for the next two hours. When dry, lightly sand, then fill surface with a low weight spakeling compound, scrapping off excess with a playing card. Sand to a smooth finish ready for primer. For heavy weight fibreglass, apply the epoxy before and after laying down the cloth. Finish-Cure is best mixed in a disposable cup.
