Many of my studs had been replaced with bolts. When I had the covers off, I put in the correct studs, as well as new gaskets, but I noticed a little leakage from the lower stud holes after driving. Originally, there was a rubber/steel washer (that's no longer available). Since the leakage is from the studs themselves, I was thinking I should reimplant them with permatex or teflon. Any suggestions?
The studs I got were not (this was for the FJ45, small (6mm) studs, and not OEM (no longer available, I guess). I would bet that goop is teflon, at least on other threaded toyota stuff it looks like it. So that's what I'll put on there unless someone says different. Thanks, Andrew.
