Mixing some epoxy and some chopped glass fibers allows the casting of couplers and other parts. I would strongly suggest that if you use fiberglass cloth and epoxy you spend a little more money and use S-2 cloth. About 30% more strength for the same weight. The pultrusions are easy. Laying up composites takes allot more skill. If you don't have someone experienced with composites I would recommend not going with it this year. Do your research and practise in the off season next year.

Is epoxy legal????
