Ive heard of a lot of guys using plasti-dip on grills and emblems. Ive even seen it on a set of wheels. Not sure how durable it is though. I even bought a bottle at Home Depot to try, but then decided to get the M5 and got bored with mods on the old car. Guess the good thing is if you mess up, just peel and respray. And its cheap. I would probably limit it to emblems and small items.
