Probably a solvent based two-stage laquer.
Mine were peeling also and I refinished the ones on the doors years ago. I still have to do the dash. I used a high quallity single stage boat varnish and brush applied it in 3 or 4 layers. The final coat I did it with a spraygun with diluted varnish. Looks great but slightly lighter in color since I didn't use any pigment in the laquer. For me that looks better with the black leather and silver velours that I have.
