Yeah Ox. I know what you mean about the etching. My previous car was a 2002 BMW 325Ci .. which was jet black.
A Goose fired a shit shot to the side fender (how this was possible? I dunno) When I went out to the car after work it was there for how long? Maybe 4 - 6 hours. I always keep my cars waxed but this etched the jet black and left a dull mark .. a reminder of the offending flying perpatrator.
