I cant believe I'm posting this but... there are a few birds at my house that enjoy the heck out of constantly sitting on my car and/or truck mirrors, and taking a crap. Anyway, I would shoot them, but I prefer not to, I don't kill it if I dont intend to eat it. Plus I'm not shooting at my car. Any suggestions? Do you think armor-all or tire cleaner would keep them away? I said I prefer not to shoot them, I didnt say that I wont.
