I believe if the paint work is done correctly, that is to say, glass, trim, seals removed and then prepared and painted properly, cleared and polished, really no issue with value. If someone just tapes off glass and trim and shoots color, now I see a depreciation of value.
If it is a clean low-mileage car, please have it done by a shop that does the work correctly and get photos in process in the event you ever sell and need to disclose the work.
