It's a long shot but you might want to check around to see if anyone local has a dry ice blaster.
I had a dry ice blast contractor come to the factory and do a demo cleaning rubber molds. We had a large steel work bench in the maintenance area. The bench was old and had multiple coats of gloss oil based enamel paint. He used the blaster on the bench and it cleanly took one layer of paint off at a time. Did not appear to change the gloss of the underlying paint layer.
Per the operator it works by thermal shock which preferentially pops the top paint layer loose from the layer underneath.
Dry ice blasting was developed to strip paint from commercial aircraft without damaging the aluminum skin. Nice thing about it is it leaves zero media residue other than what you have removed.
