POR-15 Fuel Tank Sealer was formulated and developed in our own laboratories due to the demand for a high-tech sealer impervious to all fuels, including the new Stage II fuels which have a high alcohol content. POR-15 Fuel Tank Sealer has superior strength and fuel resistance, and does not contain Methyl Ethyl Ketone, a highly flammable and deadly carcinogen (cancer-causing).

Forget zinc chromate and rust inhibitors. The only way to stop rust is to keep moisture away from the metal. Only a non porous coating can keep moisture away from metal.
And we make the only one that's been tested and proven to work with all fuels. It has superior strength and fuel resistance and is non flammable.

Though for any tank sealer to work properly the tank must be free of contaminants, hence we usually sell this product as part of our money saving kits.

POR-15 Fuel Tank Sealer is non-flammable and is environmentally safe.
