The "hung" walls are gel coat too,but the product is Filon,thin plywood,a layer of resin impregnated fiberglass matt,and gelcoat.My question is , what is the exterior wall material that is vacume bonded (vacume bagged) to the wall frameing comprised of? "gel coat" is a unreinforced,colored polyester resin which can be either orthophalic or isophalic in compossition,the biggest difference being (after cost) its ability tostand up to UV light with out degradeing.
