Phenol Novolac Epoxy Gas Tank Sealer by Caswell. Permanently Repairs Steel, Aluminum, Fiberglass and Plastic Gas Tanks. Phenol Novolac Epoxies are a new breed of chemical resistant materials, able to withstand permanent immersion of many harsh solvents, fuels and oils. This Epoxy has much better bond strength than single component products, with strengths of up to 3000 PSI. This higher strength reduces the need for a clinically clean surface, as the epoxy actually prefers to bond to a rough rusty surface. This 2 part epoxy sealer kit includes enough sealer to do 2 small or 1 large motorcycle fuel tank (more than enough needed to do an RD). This product has additional shipping charges. Kit comes with complete instructions. -
