How to Use
- Clean all surfaces thoroughly. Remove old gaskets, dry the surfaces, and remove all oil and grease.
- Remove the cap, puncture the inner seal, screw on the nozzle, and cut to the desired size.
- Apply a continuous, uniform 1/16" to 1/8" bead around the perimeter of one surface. Completely surround all bolt holes.
- Wait 10 minutes for the silicone to "skin over", then reassemble the parts.
Tips: Leave thickness for the gasket when reassembling and do not over-tighten bolts. Remove excess silicone with a dry cloth or alcohol wipe. Allow 24 hours to fully cure and bond. Replace the cap after use.
For caliper covers: apply a bead to the back of the cover, press onto a clean, dry caliper, and let it cure before driving.
