A less exciting approach is a bottle of GC Strip-X. I don?t know if
it?s still available?I don?t recommend using that as a search
term. :(
Is that GC, or MG Chemical? GC makes mechanical strippers these days.
The right answer is probably a solder pot.
Which won't work with Formvar coatings at all. There are stripped
mechanically, with rotating rubber eraser wheels that wear plastic far
faster than copper.
What would also work would be a small pot of hot lye solution.
I've used the melted aspirin tablet approach, and it does work, but the
smoke is quite noxious.
GC, as in General Chemical, iirc.
Famous for Q Dope among other radio stuff.

IIRC it smelled like Easy-Off, a lye-based oven cleaner paste, with
maybe some TCE like old time paint stripper (you know, the stuff that
actually workedPolystrippa, I think).
The problem seems to be that "GC" is heavily overloaded.

I found the original MSDS. Google for "GC Strip-X 10-2602.pdf"
(without quotes). It's Methylene Chloride, Phenol, and Ammonia.

I think the active ingredient in the old style paint strippers was
methylene chloride, hard to get these days, but you can still get solvent
based epoxy paint strippers which have substituted a solvent not yet
proven to be a strong carcinogen. Jasco Premium Paint & Epoxy Remover is
one example readily available in the US.
That's correct.
Methylene Chloride was recently forbidden across the board, so there
are no effective chemical strippers left. Other than boiling lye.
Zylene is also readily available in the US, it will strip construction
adhesive (epoxy strippers won't), haven't tried it on epoxy but it might
work. Use in something resembling a fume hood, it smells like your
olfactory nerves are being attacked by a blowtorch. Epoxy stripper is not
much better.
I don't think that Xylene will strip catalyzed films fast enough to
matter. It takes small molecules that can diffuse into the film.
The alcohol torch method is probably a lot safer, or mechanical stripping
of solid wire (hard to do on litz).
As has been suggested, wrapping the fine Litz wire strands around a
heavier lead wire and using the alcohol torch and dip method on the
whole assembly, immediately followed by soft soldering, sounds best.
