WITHSTANDS 600 DEGREES F AND FLEXES WITH THE TANK: Cured coating handles engine and exhaust heat without breaking down, and stays flexible enough to expand and contract with the tank instead of cracking.
EVERYTHING NEEDED IN ONE BOX: Includes KBS Klean cleaner/degreaser, RustBlast rust remover and metal etch, Gold Standard Tank Sealer, nitrile gloves, and complete step-by-step directions. Non-flammable and contains no Methyl Ethyl Ketone.

PERMANENTLY SEALS RUST & STOPS CORROSION: Gold Standard Tank Sealer forms a super-tough, non-porous barrier that bonds directly to rust and bare metal, sealing pinholes and weld seams in one application. Once cured, it won't crack, peel, or flake — even years later.
FUEL & ETHANOL PROOF FORMULA: The cured coating is impervious to gasoline, diesel, ethanol blends, alcohol additives, and most solvents — making it compatible with all modern fuel types including E10, E15, and E85 blends.
WORKS ON MOTORCYCLES, GENERATORS, MOWERS & MORE: Sized for tanks up to 5 gallons, this kit is ideal for motorcycle and dirt bike tanks, snowmobiles, ATVs, lawn tractors, generators, and other small utility tanks — steel, aluminum, and fiberglass compatible.
PROFESSIONAL RESULTS WITHOUT SPECIAL SKILLS: The included RustBlast prep step reduces flash rust by over 80% and creates an ideal anchor profile for the sealer, so you get a durable, professional-grade finish even on a first-time DIY project. Made in the USA by KBS Coatings.
This tank sealer is a polymer coating resistant to gasoline, diesel fuel, alcohol and other fuel additives, it's major use is to seal leaking fuel tanks (1 Qt will seal metal tank up to 14 gallon)
Easy to use if the directions are followed closely. It seals the of small leaks that often form, you fix the obvious leaks and the sealer seals the rest
Contrary to what some people will tell you, rust does form inside gas tanks. The cause is condensation and water in gas.
This sealer seals rust under the coating so it cannot flake off to plug fuel-line filters or cause engine damage. Further rusting is reduced also.
The coating is very flexible and does not crack as do some of the others. This gives the repair a much longer life.
