hi guys need some help here. I just cleaned my car and i left it in the car park at work only to return and find bird **** all over it.. I washed it off straight away but cos of the heat in sunny side london its left its bloody stain mark in the paint work! I used car wax thought might help but no good.. Wondering if you guys knew if there was anything good to remove that **** off with out damaging the paint work?
