I had some bumbleheads doing some remodeling work awhile back, and
recently I smelled propane near an exterior, above-ground run of black
pipe they installed. Tested with soapy water, and sure enough one of
the joints at an elbow is leaking. Getting this run apart so that I
can get to the elbow joint will be a hassle. Is there any way to
repair this without disassembly? Perhaps a liquid pipe dope that I
could brush on, and would seep in well enough to seal the pinhole
leak?

Sometimes you just have to do the job right. Sorry, no good shortcuts,
especially with gas. You must get the threads to close up, not use a
filler.
