Last time I did one (years ago) I used shellac as I was putting it together.
Dries pretty fast, I think it's an ok dielectric, cheap and easy to get. I
didn't wait for it to dry, I just kept going. Once it was wound and dried
overnight, I dipped it in some of that "tool dip" type liquid rubber stuff.
I worked that sucker pretty good, getting it quite warm many times and it
held up. Still have it around here somewhere.
