Fuel Tank Sealer - Quart

The POR-15 Fuel Tank Sealer in quart size (SKU POR49204) is a specialized epoxy coating designed to permanently seal and protect fuel tanks from corrosion and fuel leakage. This clear sealant creates a durable barrier that resists all fuel types, making it the industry standard for fuel tank restoration, repair, and preservation across automotive, marine, and equipment applications. Once cured, it forms a hard, fuel-impervious membrane that prevents rust and stops seepage without requiring removal of the tank.

The quart format provides sufficient coverage for most tank sizes and restoration projects, weighing 2.45 lbs with compact dimensions (4.25 x 4.25 x 4.8 inches) for easy storage and handling. POR-15 fuel tank sealer is formulated to cure hard and remain flexible enough to handle the thermal cycling and vibration that fuel tanks experience during normal operation. The product adheres directly to bare metal, rust, or existing coatings, eliminating the need for extensive tank stripping. This all-fuel-resistant composition handles gasoline, diesel, ethanol blends, and alternative fuels without degradation, making it suitable for vintage vehicles, off-road equipment, motorcycles, and marine engines.

This fuel tank sealer serves both preventative and corrective purposes: restoring compromised tanks that have developed pinhole leaks or surface corrosion, and protecting newly restored or replacement tanks from future degradation. The clear formulation allows visibility of the coating during application and curing, ensuring complete coverage. It's particularly valuable for classic car restoration, fleet maintenance, seasonal equipment storage, and any situation where fuel tank integrity is critical to performance and safety. The one-quart size is ideal for single-tank projects or for keeping in stock for emergency repairs.
