Does the coating appear to be a paint or epoxy type stuff or is it a plastic-wrap type coating? A Magic Eraser might work, test on the underside first!

Its a plastic-wrap sort of thing, so theoretically removable without too much effort. Pretty adherent where it adheres, however. I'll try the Magic Eraser--thanks for the suggestion.

Since it is some kind of plastic film there is also the option of using a razor toget an edge and peeling it. Perhaps the rest could even be melted off, but that could be dangerous if the stuff is flammable

I bought copper cookware many years ago with a coating to prevent tarnish... they suggested cleaning it with rubbing alcohol to remove the finish. That might be worth a try.

I'd try melting if all else fails.

Thanks! Good suggestions. I expect that the coating is flammable, but the alcohol might be sufficient solvent. I didn't think about acetone, but maybe that is something to try as well.

I'll let you know if anything works.

Citri-strip.

heat gun? (carefully!)
