Fuel Tank Sealer - Pint

The POR-15 Fuel Tank Sealer in pint size is a specialized corrosion-prevention coating designed for restoring and protecting fuel tanks from rust, pinhole leaks, and fuel degradation. Whether you're working on classic car restoration, vintage motorcycle rehabilitation, or any vehicle with a compromised fuel system, this fuel tank sealer provides a permanent, fuel-resistant barrier that stops active rust and seals minor leaks without requiring tank removal or expensive replacement. Trusted by restoration professionals and DIY enthusiasts alike, this product is ideal for anyone facing fuel tank deterioration that threatens engine performance and vehicle reliability.

This clear fuel tank sealer works by chemically bonding to metal surfaces and creating a non-porous, fuel-resistant coating that stops rust at its source while remaining compatible with all fuel types, including ethanol blends. The pint-size container delivers sufficient coverage for small to medium fuel tanks, allowing controlled application inside the tank where it cures to a durable, flexible finish. POR-15's formulation cures without requiring heat and produces a coating that resists gasoline, diesel, and alcohol-based fuels, making it universally applicable across diverse fuel systems and engine types.

Owners of vintage motorcycles, antique automobiles, lawn equipment, and recreational vehicles benefit most from this fuel tank sealer when they discover rust or seepage without the means for immediate replacement. Installation involves draining the tank completely, cleaning internal surfaces to remove loose rust and contamination, then coating the interior walls according to POR-15 instructions—a process that extends fuel tank life by decades. This pint unit (SKU POR49208) is particularly suited for single-fuel-tank applications and represents a cost-effective alternative to professional tank restoration or replacement services.
