They call it Scratch Guard. It's basically a coating as thick as a normal coat of paint which goes over the clear coat of your car. The paint will fix itself after it had experienced a scratch that has not penetrated the Scratch Guard coat; allegedly pouring hot water over the affected surface speeds up the process. The Scratch Guard basically contains a highly elastic resin that mends itself over time when it is exposed to a heat source such as the sun.

Another one of Nissan's countless innovations. I'm not sure if the new Z will have it. Maybe it'll be extra.
