I don't believe Philco used pure bees-wax. I think it will melt way too easily in the hot environment of a radio chassis.
The wax originally used had a higher melting-point too many sulfur compounds (as it turns out) which over time and with moisture absorption, created weak suphuric acid which corroded the copper ("The Greenies") and opened up coils 60-70 years later.
Spray lacquer is much better, as Ron advises.
