Effective Threadlocker for Automotive Use

When I tried the threadlocker for my car's fix, I was impressed with its effectiveness. It securely sealed the bolts and eliminated any loosening issues. It proved to be a reliable solution for automotive repairs. However, the application can be a bit messy and requires careful handling.

Pros
  • Effective, reliable solution for automotive repairs
Cons
  • Application can be messy and requires careful handling.

This perfectly prevents loosening of the nuts in all positions.

The reason for lowering the sprocket is because the description doesn't say that this threadlocker requires heat to remove the nut. Using a wrench on a nut without heating it to 500 degrees will not loosen the fastener. This is great for preventing loose nuts in all positions except near heat sensitive parts. It also cannot be used on plastic.

Pros
  • Fillers, adhesives and sealants
Cons
  • Not the best

Great product BUT shake well before use and you won't be disappointed!

I tested this on a test mount without reading the instructions, it worked but not very well. After seeing how well it shook in the directions (on the back) I cleaned the test cap and put it back on. After an hour it was difficult to turn by hand. I left it overnight and tried turning it on in the morning, NO GO. This material works almost as well as a well-known brand. I highly recommend this product and shipping was very fast. Thanks very much!

Pros
  • Sealant
Cons
  • So So
