Permatex Spray-a-Gasket Copper Sealant

This fast-drying copper sealant is sprayed on the gasket and has the advantage of dissipating heat quickly, which significantly minimizes the risk of burnt-out seals, in places of high temperature development such as exhaust and cylinder head. If sealing surfaces have unevenness, these are filled and immediately completely sealed. Resistant to all automotive fluids, especially gasoline.
