First, thank you Scott for having used S100 and indirectly causing my purchase of it some time ago. I love the way it looks on black. I just cleaned up my wife's friend's Mini. It had tree crap all over the paint (not really sap though) that had to be clayed out, and still has water spots in certain areas. I'm majorly concerned with the stripes because they're decals and I don't want to hurt them, and the edges of the roof. I have a rotary and a PC, 3M liquid compound and also the machine polish along with the 3 step Mother's line (dacp and swirl free polish). I was gentle to it because I didn't want to screw up the paint, will vinegar take these out without further abrasiveness? Thanks for any advice. This was just a clean up, but she will bring it back periodically so I can concentrate on one spot at a time. Here's some before and after shots. DSLR loaned out, so used point and shoot. You can really see what I'm talking about in the last 2 pics.
