KBS Coatings Gold Standard Tank Sealer, Pint

KBS Gold Standard Tank Sealer is a single component, ready to use fuel tank sealer that stops rust inside a metal gas tank and keeps it from coming back. It is the final step of the KBS 3 step system. KBS Klean cleans out varnish, old fuel residue, and grime, RustBlast removes rust and etches the metal, and Tank Sealer pours in, coats every inside surface, and drains out. The cured film is a tough, fuel impervious, translucent silver coating that seals small pinholes and weld seams, and it is compatible with gasoline and ethanol blends including E10, E15, and E85. It is a good fit for the tanks on older tractors, lawn tractors, motorcycles, ATVs, generators, small engines, and farm trucks, and it costs a lot less than a new tank. The pint seals one tank up to about 12 gallons, a fit for many motorcycle and compact tractor tanks. Coverage is about 100 sq ft per quart at 2 mils. Let it cure 96 hours with the openings open before adding fuel. Made in the USA.Prep decides how well Tank Sealer works. Drain all fuel, remove the tank and its fittings, and plug the openings. Mix KBS Klean 1 to 1 with hot water, pour it in, and soak while rotating the tank, up to 24 hours for heavy buildup; a handful of nuts or a length of chain helps knock loose rust free. Rinse until the water runs clear and dry the tank. Pour in RustBlast full strength and roll the tank every 5 minutes for 30 to 60 minutes so it never dries on the metal, then rinse and dry the tank completely with forced air, a shop vac, or a fan. A white powdery residue is normal zinc phosphate and helps the sealer bond, so leave it. Patch any holes larger than a pinhole with NuMetal Epoxy Putty. Seal within 10 days of prep, with the tank at room temperature and out of direct sun. Stir Tank Sealer thoroughly, never shake it, pour it in, and rotate the tank so it coats every surface, then drain the excess. Once drained it is spent, so never reuse it in another tank. Leave the openings open and let it cure 96 hours before adding fuel. Tanks with an old liner must be stripped first with KBS Strip.
