I've always liked beeswax; HP and Boonton Radio did also.

For 40 years the Boonton Radio Q Meter Inductors were all dipped in a pot of pharmaceutical grade beeswax- anyone in the industry has seen USP beeswax. It was my department- I dipped them at times too.

I've always used it on my coils whenever rewinding or repairing and never had any problem with it. It has the advantage of allowing repair while the modern sealers are set for life- there's no going back. Another advantage is using a microscopic bit on the end of a screwdriver to hold a screw for those difficult to get at places.
