Kemlite is simply Crane Co.'s name for their particular fiberglass formulation that is best for RV roof panels ...they have a different formulation for high gloss side panels. I note that it is manufactured as a poured liquid with chopped fiberglass in resin. My guess is that it is similar to other big FRP mfr.s engineered formulations for specific applications.
Certainly better than just run of the mill FRP since specific properties like ultraviolet protection are engineered in.
