DIRECTIONS:
For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake & Parts Cleaner.
Cut nozzle to desired bead size – gaskets are best formed using a 1/16" to 1/4" bead.
Apply a continuous and even bead of silicone to one surface, surrounding all bolt holes. Remove excess with knife at once.
Assemble parts immediately. Do not squeeze out silicone by over-tightening bolts. Re-torque will not be necessary.
Silicone dries in 1 hour, and fully cures in 24 hours, at 70F (21C) - 50% relative humidity. Allow more time in cold weather.
Replace cap after use. Clean hands with dry cloth or Permatex® Fast Orange® Hand Cleaner. Clean tools with non-flammable cleaning fluid.

Not recommended for use on head gaskets or parts in contact with gasoline.
