Working on a GE that (like many radios of the era) needs all of the
rubber-covered wire replaced. Slow and tedious to be sure. There are some
wires that have started to crack but haven't crumbled yet, but unfortunately
are in places that I'd really rather not dig into - particularly coming from
the transformer cans. Sure, I could dissasemble the cans and replace the
wiring, but instead I decided to try coating the wires with clear liquid
electrical tape. I found I could use a very small brush and coat the
wires - even reaching up into the cans a bit. It worked great. No need to
replace the wires, stopped the crumbling, and restored the original wires to
a safe and reliable state.
This turned out to be much easier than the alternative that I know some
people use, which is to unsolder one end and slip a length of shrink tubing
over the wire.

What brand of stuff did you use?
Phil Nelson
I've used the black stuff for years, which is what gave me the idea. Very
tough stuff when it's dry, and it does dry quickly. Here's the clear stuff
I bought - it's
Star Brite brand. I called around and couldn't find clear locally - all
anyone had was black and red.
I bookmarked that. Looks like handy stuff.
