I've worked on Corvettes, I do know the paint can crack ( actually may be the fiberglass underneath) if they are lifted improperly. But as far as polishing paint, I do not see anything special you have to do to it that you wouldn't do to an ordinary car aside from maybe never leaning into the polisher when working on swirls. If the car had a lot of swirls I would just make several passes instead of trying to lean into them to put more pressure on the swirls to get them out.
The swirls I saw on the Vette I did must have come from a rotary and if a rotary is safe enough to use, aside from putting swirls in the paint, which it could do to any car's paint, then my PC is certainly safe for it. Got swirls out successfully with the PC.
