I rubbed one of my wheel arches against a painted poll. And now there is white paint transfer on it. Luckily it didn't scratch the cars paint. What is the best way to remove the white paint without scratching up my car? My car is quartz grey if that matters.

 

Best way is to get some 3M rubbing compound - medium cut - on a regular buffing/applicator pad. Use a little elbow grease - might take a while. Afterward you should use apply a good polish, since the medium cut might dull your clear coat slightly.
