Bird crap has made a large-ish 'matt' patch on my wing (black car).
No 'raised' damage to the lacquer, just a matt patch in the shape of the crap.
I tried using the following, which was all I had in the garage, with some success.
1/ Turtle wax scratch and swirl remover
2/ Meguires Crystal polish
3/ Collinite wax
A 'passer-by' wouldn't see the matt patch now, but I still see it, in parts.
Any suggestions as to a good product???
For future use, if nothing else.
