We'll see how long it lasts...post your observations of this
I've been using Mothers Back to Black for some time now. It does a good job of hiding the white residue on the black panels, however I've noticed it only lasts a week or two at best. And of course if it rains, then the white marks are back. I have used pb and that has worked well on my previous car, haven't had to use it just yet on the '02. I wish BMW would just make them body colored, I wonder why they don't??
