ALUMINUM DE-AIRING ROLLER (FIBERTEK) 3/4" x 3"

These uniquely designed ribbed rollers are essential for quality fiberglass work. Once saturated, the material is then rolled with the roller and the entrapped air is removed. The rollers compress the layers of fiberglass together giving a better glass to resin ratio, making the laminate stronger, lighter and saves money as less resin is used. Should be cleaned with acetone.
