I have used he above method to remove the lacquer and epoxy from Church Chalices dozens of times. I really wouldn't fool around with chemicals and witches brews.It's really not hard to polish them. You can make just about any grinder motor into a polisher.pm me if any of you would like some help to do this.

This solvent Rings and Things used was specific to this finish. You could dip a cup into it for a couple of seconds, and the finish was completely off of it.

That finish was put on with an electrostatic charge and baked.

Sounds like Trichlor- great solvent - bad for kidney function and risk of cancer - I was just told by a friend that it can't be used in L.A. any more .

Could be. I think it was a mixture of several solvents. It had a trade name like Hot Shot or something like that. Back in the "good old days" these mixtures like Trichloroethane, MEK and acetone, were fairly common. But normal paint remover wouldn't even touch this stuff.
