Freeing frozen bolts and parts.

TC-11’s superb penetrating characteristics easily fill the interstial spaces in frozen parts for unparalleled unlocking of frozen bolts and parts.


  • Spray frozen bolt or part with TC-11.
  • Wait 10-30 seconds.
  • Apply torque in a back-and-forth motion. Repeat steps 1 to 3 if necessary.
  1. Apply a small amount of TC-11 to the moving metal parts.
  2. After 20 minutes, wipe off excess TC-11.
Electrical System Waterproofing

Apply TC-11 to spark plug boots, distributor cap, coil or coils, battery terminals, multi-pin connectors, and terminal strips. Do not apply directly to fuse labels or other sensitive adhesive labels. Do not apply to arcing contacts. TC-11 is an insulator that will cause a small voltage drop across the connection that does not increase over time. An untreated connector will corrode and the voltage drop will increase until the component no longer functions.

Long-Term Storage: If equipment is to be stored for more than five months, apply a heavy coat of TC-11, wait 20 minutes, and apply a second heavy coat. Wash down equipment with a water spray to remove any dust and debris.

Sporting Goods
  1. Apply TC-11 to fishing reels, guns, PWC, ATVs and other metal equipment 48 hours prior to use.
  2. Clean equipment after use.
  3. Allow equipment to dry.
  4. Apply a thin coat of TC-11. Apply two thick coats of TC-11 before long-term storage periods.

I put TC-11 on a metal overhead door that was difficult to operate and it was making a lot of noise. As soon as I put TC-11 in the operating mechanism, it was much easier to operate and it no longer made any noise. The amazing thing is that this was three years ago, and the TC-11 is still doing its job. When I applied the TC-11 some of the over spray landed in a fish pond that was below the door. I figured that the fish were in big trouble. It turned out that the TC-11 had no effect on the fish. I recommend the product to everyone”.GLEN – KAILUA, HAWAIIGLEN – KAILUA, HAWAII.
