I'm interested in this question, too. Also for curiosity's sake. I saw a 2009 Flat Black Nissan GTR at the movies the other day. It was definitely SICK, but I had to wonder how you might care for this paint. You couldn't buff out scratches, as it would produce an uneven shine. You couldn't repair rock chips or deep scratches, as even matching flat black from the same batch applied at different times doesn't match. And thus, I would imagine that ANY bodywork done to the car would require a full repaint so that it all matches.
I would also imagine that this was a total custom job (though I have a hard time fathoming repainting a new car right after it was bought). I know that some of the GTRs have that new "self healing" clear on them, but it couldn't be with this job.
We talk about how hard it is to keep swirl marks off even our pampered cars, and the pain of rock chips and such, but compared to this scenario, it would seem that we have it easy! Jeez, you'd have to keep the car in a bubble just to preserve its paint! A car like that wants to be driven hard! Seems a shame, if this is the case with this paint.
Maybe some of the guys more familiar with this sort of paint might be able to help answer this question!
