After looking at the pics, I would say that the color changing is kind of a gimmick as I am not impressed at all. I would rather have a super metallic paint that gives a 3 d look by means of the shadowing.
Be SURE to have epoxy primer used as the other is cheap crap! After a lot of research, I chose Imron. Imron is considerably more resistant to sun, chemicals, smog, etc., and is a genuine polyurethane paint. Check it out! Get a copy of the Imron Metallic paint chart, really great colors with that shadowing quality! Also, Imron is one of the easiest to paint as it lays out beautifully in a perfect gloss.
Some painters avoid it as there is only about a half hour of "rub out" time, and the paint is so hard and tough a finish, which is great for you to have super sturdy finish, that it is almost impossible to rub out if they wait too long and then will have to shoot another coat. so get a shop familiar with it.
Andy don't let anyone BS you about isocyanates of Imron vs others as they all use isocyanates if you look on the label, and the isocyanates improve the lasting qualities of the paint, and Imron will outlast any other paint. Use two or three clear coats.
