So I happened to make contact with the White wall in my underground parking Just a gentle nudge ,but enough for some paint from the wall to scrape onto the plastic above the Chrome bumper. Anyone have a good suggestion of how to get the paint off the plastic would be appreciated.

 

I would try a clay bar first then a rubbing compound if that did not work.

 

I used to use a liquid rubbing compound for stuff like that. It worked great and was not too abrassive.
