KBS Coatings Cycle Tank Sealer Kit — Complete 3-Step Fuel Tank Repair Kit, Lightly Pigmented Silver for Up to 5 Gal

KBS Coatings Cycle Tank Sealer Kit is a complete three-step system that cleans, etches and seals fuel tanks up to 5 gallons with a long-lasting, fuel-resistant interior coating.

Restore or protect small fuel tanks with a single kit designed for do-it-yourself mechanics and professionals alike. The package includes a heavy-duty degreaser, a rust remover/metal etch, and KBS’s Gold Standard Tank Sealer in a lightly pigmented silver — plus gloves, a stir stick, and clear instructions so you can complete the job without sourcing extra products. The formula bonds to bare metal and rust, cures to a non-porous film, and resists gasoline, ethanol blends and common additives.

How does the three-step process prepare and seal a tank?

The kit follows a logical sequence: clean, treat, then coat. Each step is formulated to maximize adhesion and longevity of the sealer so the interior surface becomes a continuous, protective barrier.

• Step 1 — KBS Klean: removes grease, old fuel varnish and contaminants for a clean surface.
• Step 2 — RustBlast: chemically strips rust, etches metal and reduces the chance of flash rusting.
• Step 3 — Tank Sealer: forms a durable, non-porous film that bonds to treated metal and rust.

Will this sealed finish tolerate modern fuels and additives?

The cured sealer is designed to handle contemporary fuel formulations and most common additives without softening or breaking down. It’s tested to resist gasoline, diesel, ethanol blends (including E10, E15, E85) and typical alcohol-based additives used in everyday engines.

• Fuel compatibility: gasoline, diesel and ethanol blends supported.
• Resistance: impervious to most solvents and alcohol additives when fully cured.
• Durability: formulated not to crack, peel or flake under normal fuel exposure.

What kinds of tanks and materials can I use this on?

This kit is sized for tanks up to approximately 5 gallons and works across a wide range of small utility tanks. It is suitable for steel, aluminum and fiberglass fuel tanks commonly found on motorcycles, ATVs, mowers and portable equipment.

• Vehicle types: motorcycles, dirt bikes, snowmobiles, ATVs and lawn tractors.
• Equipment: portable generators, small utility tanks and similar reservoirs.
• Material compatibility: steel, aluminum and fiberglass interiors.

How much preparation and skill are required to get professional results?

The kit includes products formulated to simplify prep and deliver a reliable finish even for first-time users. Detailed, step-by-step instructions and included consumables (gloves, stir stick) minimize guesswork; careful attention to the prep steps yields the best long-term performance.

• Included guidance: clear instructions guide each stage from cleaning to curing.
• Tools provided: nitrile gloves and stir stick reduce the need for extra purchases.
• Prep advantage: RustBlast reduces flash rust and improves sealer adhesion for a stronger bond.

Who this is for: This kit is aimed at motorcycle and small-engine owners, hobby mechanics, restorers and service shops who need a compact, all-in-one solution to repair or protect small fuel tanks. It’s practical for anyone maintaining or refurbishing tanks up to about 5 gallons who wants a fuel-resistant, long-lived interior coating without sourcing multiple specialty products.
