Am pretty sure this was an acoustic machine.
I am assuming this was some kind of wax ?
I've tried ordinary candle wax and it leaves a mess (perhaps no problem other than cosmetic) which is very hard to get rid of, no matter what washing and buffing. Beeswax might be better, I will try it sometime. Back in the day, EMG sold a waxy preparation for exactly this purpose - I have some (long since dried out) in something like a lipstick tube.
I recently bought a few records that were part of the collection of an EMG owner and they were "scribbled" all over with wax. Same problem, but otherwise they're near mint and play perfectly.
I've also tried graphite powder, another material that was used back in the day - VERY messy, it gets everywhere, even when you think you've cleaned up thoroughly! But it extracted much better sound from a badly worn record.
I would only ever use anything like this with a "difficult" or worn record, never routinely.
