I just got the Griot's machine wax kit which includes an orbital machine, pads, polish, and Best-of-Show Wax. The quality of the wax is excellent, but there is a lot of residue, though. The shine, however, is outstanding (esp. after using the clay bar and machine polish to remove any swirl marks)...much better, in my opinion, than Zymol or One Grand Blitz Wax which I used previously. (BTW, I have a black X5 also)
