Is there a way to use the PC on this? I imagine you could, however, it would miss the sections that are lower than the rest. Is this something that is required to be polished by hand? If so, is there anytihng I can do to speed up the process? I have a Caravan coming up, and this will the the first vehicle that I have detailed with a corrugated roof. Just wandering which approach I should take. TIA! :woot2:
