I picked up a used car recently and noticed that it got hit with some idiot's paint overspray at some point. Not sure how old it is, presumably much longer than the 3 weeks I've owned it. It is a fine mist. Thousands of tiny whitish specs everywhere on one side of the car. I'm assuming it is a latex based paint considering I can scratch off some of the spots with my nail with a lot of effort. I easily removed paint from the windows using a razor blade. I'm assuming for the paint I can probably start by using the least abrasive polishing compound to gently remove the overspray. I'm not sure about how to tackle the chrome and plastic though. Tomorrow I may try a credit card to see if this will do the trick as I don't think that should harm the surfaces too badly. Any tips/ideas on how to solve my problem?
