I started re-stuffing wax paper capacitors back in the 1970's. Also re-painting resistors with body-tip-spot color coding and re-wiring sets with fabric wire. I got a lot of very odd looks from other technicians back then.
Over the years I found the ideal method for wax-paper caps was to heat them in an oven until the wax just melted. Then pull and or push the innards out. The trick then is to wipe the paper tubes down with a paper towel, that absorbs the dirty melted wax.
On fitting the new caps inside, fibreglass tape is used to build up their diameter, to a push fit in the sleeve. Then, on alternate days, polyester resin (the type that uses a catylast) is poured into each end. This has an opaque look to it, somewhat like wax, but won't melt or attract dust (Photo of some from a TV restoration attached).
