Fuel-Resistant Surface Fillers

Also known as sloshing compounds, these two-part epoxies bond to rough and rusty surfaces in fuel tanks to repair leaks and prevent further corrosion. They withstand permanent immersion in fuel, oil, and harsh solvents. Use them with metal, plastic, and fiberglass tanks. Mix the smaller can with the bigger one and pour into your fuel tank. Rotate the tank to coat the interior and dump out any excess. Allow to cure overnight. Size listed is the combined total of the two parts.

1.5-pint container can treat a 10-gallon fuel tank. 3-pint container can treat a 20-gallon fuel tank.
