I've used it on my Black Crossfire, actually 2 coats and it seems to be working extremely well. The color is very rich and the bead is amazing even after 3 weeks of really crappy weather. Also the tech wax on the wheels was awesome, basically just spray some water on them and the brake dust melts away (Still SOME scrubbing required...). Overall, from the reviews i've read and my experience, this is some pretty amazing stuff concidering its ease of use and performance. Good luck.
