Would this insulating varnish from McMaster work? Only $7.25 per can.

I found this stuff on Amazon. Maybe the same stuff?

Yes, same stuff. This is a class H insulation. It will maintain it's electrical insulating properties up to 180C/356F. "Glyptal" is used to paint the inside of utility oil filled transformers. Transformers will not get to 180C but neither will the interior surface of your trans pan as it is air cooled on the outside.
