Keeping the yellow clean?

I was out washing my car today, and I noticed I had a lot of small tar marks, some grease/oil, and other black scuffs...Now I don't know about you other yellow stang owners, but to me, those black marks stand out like a sore thumb on that color I bought this turtle wax bug and tar remover, but it didn't seem to work too well. And on top of finding that stuff on my car, it's "love bug" season so when i'm out driving, those things land on my car. soon as the sun comes out, they're almost impossible to take off, and seem to leave an annoying mark behind...my front bumper seems to be getting the worst of this. Anywho, how do yall remove that crap? I don't want to get a bra...but right now i'm starting to think i might have to.

Ok, wtf, I also noticed today that there is cracking going on on the back bumper...it's not major yet, but it's about 1 by 5 inches of paint starting to look like it's scaling or peeling off...i've only had my car for a year!
