You could just do what I did to the sun rotted and cracked "3.8l sfi bullshit" badges on my GN......sprayed them bitches with rubbing alcohol and lit it on fire. They fell right off. Nothing, and I mean NOTHING would get them damn things off. Judging by marks under them, and by the marks left when I pulled the door belts off, I would say they were put on when the clear was still tacky.
Pin stripes?!?!?! Heat gun/hair dryer and a plastic razor blade or your thumbnail, then get out the buffer and fix the scratches. There are little buffer wheels designed specificlly for getting pin stripes off but I've never trusted them.
