Nissan has developed a polymer based paint that will heal itself if it is scratched. They claim that the scratches will heal itself over a few days time. They are going to release this paint on a future SUV that they haven’t announced. This paint as compared to the regular paint on today’s cars will suffer one-fifth less scratched going through a car wash. But, in no way does this mean that you can go to the next guy’s car and key his vehicle. Man rule number 1: Never key another man’s vehicle.
