This review is from: Permatex 56521 High Performance Thread Sealant, 50 ml Tube (Automotive)

used when installing a fuel pressure sender into a 7th supply line (for 7th injector) on my v6 pickup. Also used it when making air tight seals for my air compressor (overkill maybe, but works great!).

I'm trying to find other threads that need to be sealed just so I can use it more.
