Hey all,
Have a 3 week old G37S sedan that sat on sales lot for about 4 months or so. I have what looks like some tarnished brown spots (size of a pen tip) on all of the exterior silver door trim (between seal and paint). I have tried cleaners and tarnish remover and neither worked. Any ideas?

Yep, this is the dealer's problem to solve. I would recommend that you not try any more homebrew solutions, since they may blame those for the problem, or for making it worse.
