The KBS Fuel Tank Sealer Kit is all-inclusive containing everything you need to seal a tank of up to 25 gallons.

KBS Tank Sealer is a superior, single-component, ready-to-use fuel tank sealer.

KBS Gold Standard Tank Sealer is specifically formulated to stop rust and corrosion by forming a tough, fuel impervious coating while simultaneously sealing small pinholes and weld seams.

This all-inclusive kit contains our KBS Klean (a water-based, heavy-duty, cleaner/degreaser) and RustBlast (a powerful rust remover/metal etch) to obtain a permanently sealed, rust-free fuel tank. These KBS prep products are formulated to promote adhesion of the Tank Sealer by leaving an ideal anchor pattern and also leaving a zinc phosphate film.
