Coolant-Resistant Surface Fillers

Repair small leaks and cracks in coolant systems for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems. Pour them into your coolant to fix both internal and external leaks. They contain ceramic microfibers and copper particles to create a permanent seal. They’re compatible with antifreeze and other coolant system additives.

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.
