I got one on my car today - little poop looks like a small string. When I removed it with the use of a detailer spray, a yellow stain was left behind. I got out the Ol' McGuire's Cleaner wax and buffed and buffed to no avail - I am insanely anal as well and that is just p**ing me off - it's pretty hard to see but I know it's there, and on a Brilliant Silver Metallic it shows if you know what you are looking for and where... I'm going to keep monitoring this thread see if anyone has any luck with whatever compound that might be out there... Jeez...
