Does anyone know how to tell visually, the difference in fiberglass cloth that is compatible with epoxy or polyester? I have some that I stored years ago and I don't know which is which for the ones I didn't mark.
Thanks Bob
 
Agree the cloth doesn't matter; epoxy resin will attach to just about anything. Polyester resin will not stick to epoxy resin. Epoxy sticks to poly resin.
