Hey guys, I work at a paint correction and ceramic coating shop here in Alpharetta, GA. Our experience is as you are all finding that piano black, especially on exterior trim should be banned and sent to the moon. It’s incredibly difficult to take care of and the finish will be marred from the day you take delivery. Depending on your level of scratching, correction and coating of paint protection film (PPF) is the best option. You can correct most, pretty well so long as they haven’t been thrashed with a Lake Country Blue or Oberk Yellow foam pad. Meguiars 210 should work well enough to cut and sometimes finish. If you want to step it up to a heavier compound like 110 then have at it, it’s just gonna be more work to finish out. Then finish down the marring with something like Shine Supply Slickback and a yellow foam pad. Once you achieve a good finish you are honestly best to have PPF installed, it has self healing properties that are ultimately the best protection you can get for your paint.
At the end of the day guys, these parts of your car are virtually impossible to keep looking perfect, all the time. Best you can do is get them to a good point and PPF or Vinyl wrap them and ceramic coat them
