we make money not art reports on self-healing paint for Nissan cars:

Nissan has invented a transparent vehicle body paint that repairs scratches on its own. Even if the car is attacked with a Y10 coin the paint should be able to cope with the damage. Within about a week, the paint will repair the scratch. "Of course, you could speed the whole process up by pouring some warm water over the affected area — that would probably repair it in a matter of minutes," explained a spokeperson.
