I enjoy building kits and have built quite a few over the years. I have done 5 or 6 in fiberglass cloth and polyester resin. They came out fine, but it can involve a lot of wet sanding. As i get older, I am also getting lazier. My question is, is the z-poxy system of covering with epoxy and fiberglass cloth easier than polyester resin? Does it sand easier? Is it durable? Easy to paint? Thanks in advance for your help.
