Maybe suspend a cat above your car? But then that would probably mean the cat would poop on your car instead. Seriously though, I feel your pain. There is nothing worse than looking out of the window to see a massive pile of bird poo baking in to the paint work of your pride and joy, especially just after you have slogged away cleaning the thing prior to the incident.
Is the car left all day? If so, why don't you put a car cover over it. Wash it off when you get home, ready for the next day...just a thought especially if they're using your car as a toilet.
hi all, is this stuff worth putting on to help protect 1s car?http://gtechniq.com/about-gtechniq/crystal-serum/
