does anyone wipe this stuff off when you see it? i get bird poo a few times a week, i guess my car is a prime target since it's so nice. but i don't get how they can aim that well considering my outstanding acceleration. i found if i don't wipe it off for a month, and wash my car, it still comes off with ease. but is that bad for the paint? i don't want to touch bird shit 3 times a week.
