In case anyone is taking this little side thread seriously, I would advise
against it. Heating steel in the presence of oxygen can cause metallurgical
changes that render it unsuitable for its original purpose. The usual
result of blasting out a stud with oxygen, is hardening of the metal in the
vicinity of the hole, so that taps and drill bits just break off in it.

Thanks for the follow up. I am curious, do the back hinge bolts on the
TJ use that thread sealer like the windshield and door ones on the older
Jeeps use? Could save someone some paint maybe some day...
