I am going to try this in black on my single hood stripe in contrast to a semi-gloss body color for the rest of the car.
I agree with Hdesign in that I think it works better as a stripe or hood color to create a nice contrast to a semi gloss body. There are many examples of that and I think it looks killer. Of course, to each his own. I also thought about doing the whole car in a flat/matte but decided against it.
Good luck!
