Didn't ever realize it was such a problem never ever really paid any attention to it. Always tried to keep my cars clean ,by trade been a cab driver so it has really been part of the job and once a week go to local hand car wash. Would normally do same for my golf just got a bit lazy massive piece of bird poo on bonnet sat there for a couple of weeks. Decided to go to hand car was which i normally use. It seems to have eaten away at the top layer of lacquer. Good thing it didn't take away any paint. just get really worried about bird poo getting splattered on the car. Who would have known the little pigeons are dropping weapons of destruction. Just be careful guys, sorry if anyone is offended by bad language
