Acetone is suprising gentle on most of the painted surface I use it on, cars, bikes, household, etc.
I used to use acetone as glue for airfix kits. And disolve the plastic of airfix kits in acetone to make filler. Admittedly that's polystyrene not "all plastics" nor "all paint" after all, the stuff comes in plastic bottles (polypropylene I'd guess) but I'd still be cautious on an unkown material.
