Seems to be 40% PTFE powder in some sort of carrier
This makes me wonder if teflon tape might not be something useful for
fasteners? Same sort of mechanism of creating a barrier (although t-tape in
plumbing fittings gets split at the peaks of the threads on both sides, but the
“side of thread to side of thread” mating surface has a teflon barrier (and
seal).
As for aluminum tubing to aluminum tubing - the question would be whether you
make electrical contact (which is needed in an antenna). But conceivably, you
only need a few small points of electrical contact, while most of the contact
is for mechanical reasons. So a coating of something like t-tape (not quite all
of the joint covered), would help it break free for disassembly, but leave some
(which might bond) for the electrical connection.

What a great posting, Patrick. TT proves its worth again.
I think this may be the winner. I would like to ask if it is less messy
to use on SS bolts than the anti-seize they sell at auto stores. That
stuff works well in my experience, but makes a big mess.
