It all depends on what is meant by "polishing." To clean up the finish, Meguiars is a great product. If, however, polishing means hand-rubbing to high gloss, that is an entirely different matter. For that you need to sand at 800, 1500, 2000 and 3000 grit to flatten the surface and then polish (wheel out or hand polish) with scratch remover and a couple of grades of rubbing compound. If, in the process, you sand through the lacquer, you have to re-shoot the finish.
