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.

Great stuff.
Love this stuff. I have used it before to seal cracks, minor scuffs in my tonneau cover. Dries well and remains flexible.
