I'd love to see that painted on a car.
Just noticed that you can see a little light being reflected along the bottom edge of the sphere.
That would be insanely cool. Especially if the rest of the car wasn't done with this. (trim, wheels, lights obviously, etc.)
Only if you wanted your car to get to 160F + in the summer time.
The darker the color, the more heat it soaks up.
The A/C in the car would not be able to keep up in a sunny/hot environment if it was painted with that stuff.
