Chopped strand mat, in fabric form, is sold on the roll and in small folded packages. It is made up of 1"-2" long fiberglass strands that are randomly oriented and typically held together with a styrene-soluble binder that acts like glue connecting the fibers. The binder is designed to dissolve upon contact with styrene in polyester resin or vinylester resin. Once dissolved, the fabric softens, allowing it to drape around curved shapes Epoxy does not dissolve the binder.
Could be a problem.
Thats another phone call then.
