for some reason birds take very small craps on my z once in a while but by the time i wipe it off these a yellow leftover that looks like its in the paint. I tried to wash it off and use bug/tar remover to no avail. ANyone with a white z have this issue, also whats the BEST thing if anything at all to use to get rid of bird crap stains (yellow stains on white dont look too good)

 

I would use a mild polishing compound in the 3M Swirl Mark Remover and then re wax with your final finish wax or polish.

 

I have a white Z and I have seen the same thing. I know what you are talking about and it makes me mad everytime I see that. But so far all I do is just wash and the spots that I have seen have gone away after a couple days. So I couldnt tell you what to use to get it off right now. It bothers me too.
