DIRECTIONS FOR USE:
Remove all previous material from mating surfaces.Permatex Gasket Remover is recommended for most materials, not for plastics or painted surfaces.
For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex Brake and Parts Cleaner.
Remove cap and coat with brush-top applicator.
When used as a gasket dressing, spread product with a spatula to a uniform film on one side of gasket and then position it on the assembly.Coat the second side of gasket an re-assemble. Slower drying formula increases work time.
Assembly is operational after 4 hours, full cure is effective after 24 hours.
