Default Re: Diff leaking around the bolts

Permatex #2 is not just another silicone.

There is no silicone in Permatex #2.

Permatex #2 is a sealant that is alcohol based.

Silicone based sealants were developed during the "Space Race".

Permatex #2 was developed during WW2 to seal aircraft engine interfaces where precision mating surfaces needed to be sealed, and the variability of a squished paper gasket was unacceptable.
