I differ on this. I have several coils that I wound over 20 years aga and
coated with polyurethane and they are as good and as nice looking as the
day they were dried! The alternatives you mentioned; G.E. Glyptal and
Dolph's AC-43 air dry varnish, are needlessly expensive when compared to
either polyethylene, Shellac or Varnish, all of which work quite well.
BTW there may be differences in polyurethane finishes, I used Zar brand,
clear glossy, oil based.
Sincerely
