Top-of-the-line

Fabulous deal for the money, especially given the fact that Permatex products are considered top-of-the-line by every mechanic %26 repairman I know. It seals everything it claims to be able to seal %26 solved a problem of rain leakage into the trunk of my car that has existed for more then twenty years, while other products failed to do the job. Kudos to Permatex %26 to this supplier for making it affordable, unlike other sources of the same sealer.

Works great when you need black silicone

Used this to seal my truck bed cover that is about 15 years old--works great in all weather. Will buy again if necessary.

A GREAT FIXER UPPER

I have a an old car and I got this to fix some of the rubber seals on it BOY does it work really good. This stuff saved me some money on having to buy the rubber seals for this car. Buy some of this to fix what ever you need to fix that you can use it on. It will save you some bucks
