I used in on my models (yes it the same paint, I got a sample jar when I was asking the company about it). form my impression the paint scratches pretty easily, but I only put one coat on my models. I would assume that a couple of layers of clear would fix that, but I tried and am unsure if the paint does well with clear coating.
I decided not to pursue investigating it any further because its techically illegal to do that, because it would be a "destraction to other drivers." I guess it would be good if you put it on in a subtle way, kinda like how its not put on all over the place like on the 3rd pic, just to accent certain areas.
Edit: Also like black, it will show dents and blemishes alot more easily
