I noticed a white paint scuff on my 2006 black Acura TL, as if someone opened their door and scuffed it on my panel. It left a layer of white paint, and its caked on pretty good (Doesn't easily come of when attempted to finger scratch it off). What's the proper way to remove this scuff?

 

a good claybar'in should take that off, ive claybarred my car before for overspray, bugs, and many other contaminents

 

Mother's Clay bar will do the job
