Nissan Motor said Friday it had created a paint that repairs scratches on its own, restoring a car’s surface to normal within a week.

The Japanese automaker said the paint contains a newly developed resin that can stop scratches from marking the car’s outer layer.

Wear and tear due to everything from fingernails to roadside objects will disappear in one day to one week depending on the temperature and the seriousness of the scratch, Nissan said in a statement.
