Nissan Makes Paint That Heals Scratches All By Itself For $400 extra on its future cars, Nissan will provide you with its new Scratch Guard Coat that is not only more resistant to common wear but also heals itself in about a week. Isn't this how "The Terminator" movie started? This gives me an excuse to start building one of those cool dune buggies with the M-60 turret on the back. I am going down swinging ... and looking really cool, because I do love to blow up some stuff. If Nissan really wants to improve their cars, they should make one that automatically drives when an Asian woman is behind the wheel.
