I would buff out that paint job. MBZ original paint is amazing . . . it can be buffed out and look brand new after sitting in the sun for 30 years, and does not fade, . . . . ever, which is why I would do whatever possible to preserve what is there, and pay to have MBZ paint used on bodywork, if small. Unfortunately, the one I bought had been damaged before by roof tiles in a storm, and repainted with clearcoat, which was peeling like a bad sunburn when I picked it up. Unfortunately, I didn't have $6-$9K to invest in a true MBZ paint job, but had a fair decent acrylic enamel (they slipped metalic by me) put on the car. Actually looks nice. Five years later is ready for its first buffing, but it holding up well with regular wash and wax. So, you should be able to buff out your paint job, and the exposed part will match the part that was covered by partial shed without any problems.
