I would love to do this but I have sort of a problem. Every morning a robin goes and sits on the roof about either passenger window and does his business on the sides of my car. And every time I go out to drive I have to wash my car. Given that, I think that it would be pointless to wax it at this point.

I am thinking of hanging plastic bags from my mirrors so when the wind blows the sound will scare him away. After a while maybe he will get the hint.
