Just washed the black XF, and the Wifes pearl white B9 Tribeca with Meguiar's Ultimate wash and wax. I have to say it did a great job on the B9, but not so on the XF. I used a car wash brush on the B9, and a new microfiber mitt on the XF. I see swirl marks on the black paint in some areas. It looks good, but not great. Also, turtle wax wheel cleaner is awesome.

Anyone have a favorite product for their black cars?
