: Does fiberglass cloth deteriorate in any manner if stored for several years
: before using. I had purchased 60 yds of 6 oz a couple of years ago that I
: haven't put to use yet. It has been stored in its original carton (rolled
: and plastic wrapped) in the house, and I am wondering if it there could be
: any problem getting the epoxy resin to adhere and wet out properly on my
: next build.
: thanks
