rubbing compound or claybar. Be careful with both. I used rubbing compound to remove some road paint(yellow) on my sister's lexus. If you are careful enough, you can use like 1500-2500 grit sand paper on it if the rubbing compound or claybar wont take it off. If it needs to be sanded, sand it a lil then use the rubbing compound or claybar and it should come off. Follow that with a polish and wax.
