Glass cloth for polyester and epoxy resin?
I'm in the process of repairing my parent's motor boat and need to glass over an old intake hole in the hull. I've been using the West System epoxy resin recently on other repairs, but I can't get any woven cloth locally that says it is suitable for epoxy resin. The only cloth I can buy is made by Bonda and states it is for Polyester resin. Is this just an advertising trick to make sure you buy their polyester resin, or is it more fundamental than that and not compatible with epoxy resins?
I remember reading once that the binders in csm are specific to the resin as to how they dissolve to ensure good wetting out, but I can't imagine there's a need for binders in woven cloth.
