I have a 2010 Volkswagen Golf 1.4. On return home from a recent holiday in Cornwall I proceeded to remove bird muck from the metallic paint. I was appalled to find that it looks as though acid has been splashed on the paintwork, made even worse by my attempts to get it off. Clearly I should have been more diligent, but I was equally lax with my last Golf, and cars previous to that, without encountering any paintwork problems. Has Volkswagen changed the spec of its paint and, if so, do all new cars suffer from this problem? I love my Golf but I can't go through this again.
