Its winter and I needed to fiberglass the hull of a new boat that I'm building. Polyester was out of the question, that is, if I wanted to stay married. I bought epoxy resin with the fast ~1 hour hardener and it worked beautifully. Check them out on the web page above! Here, you can obtain just about any resin based product and all manner of fillers, fibers, fabric including carbon fiber and Kevlar. Plasticare is in Denver Metro, but will ship your order.
