Hi slvr-bullet,
I would first recommend the least abrasive produce like 3M SMR. You can do it by hand or machine. Are going to be using a oribal polisher like a PC or are you applying it by hand? 3M carries a fine line of products to cut down on imperfections on your paint. I use the 3M SMR on my silver car and have to say it is pretty good.
Aloha,
Ranney
