This has never happened to me before with bird crap....I have two bullseyes from a bird that actually etched the clear coat on my car. I've tried 3M Imperial Hand Glaze, EZ1 Clean Cut and 3M Perfect It Polishing Glaze and a Clay Bar (Not in that order) and nothing helped...Didn't do a thing...
I tried the new Blackfire line of automive products and I was VERY impressed with the results. Much easier and quicker to use than Zaino with the same results. I'll see how it holds up over the Hot summer here in the Chicago area. I'm posting some pictures below:
