POR-15 Fuel Tank Sealer POR-15 Fuel Tank Sealer was Formulated for metal and developed as a high-tech sealer that is impervious to all fuels, including the diesel, DEF additives, E10 ethanol, and high alcohol content fuels. This gas tank sealant comes in a silver color and has superior strength with fuel resistance. Also, this fuel tank coating acts as a liner and stops rust, corrosion, and small fuel leaks. Fuel tanks must be free from plastic parts, contamination, and be structurally sound before applying sealer. Gas tanks should be free from loose rust, old sealers, cleaned with POR-15 Cleaner Degrease r, and etched with POR-15 Metal Prep for best adhesion.
