power steering thread sealant

[JimT]

So this was the stuff I used, Gasoila, It was the only thing I found at the local auto parts store at the time. supposed to be good from -100F to 600F and up to 10,000 psi liquid. Seemed to work at first, but slowly failed over time. Says it doesn't need to cure before pressurization, but some reviews on Amazon seem to disagree, so maybe that was the problem? The threads had been coated with a hardened white-ish sealant when I disassembled it, so maybe the non-hardening sealants are not optimal for this application? IDK
