Quite a bit more than Braycote, I'm sure. And it would be nowhere near as
good. But if I were restoring a $25,000 machine, spending $250 on 10 grams
of Braycote wouldn't seem outrageous. Sure it's more expensive the going
to the Texico station for a can of motor oil, but it's also not going to
eat through the decaying rubber belts within a few years.

Braycote isn't a PTFE-enhanced petroleum based lubricant. Those have all
the disadvantages of the base lubricant (which can evaporate or change
chemically), but with added PTFE.

Probably. You just shouldn't get it (or its evaporation or decomposition
products) on anything that that might react badly to them or get too warm.
