This is a special car wash

NEW CAR PAINT  The Japanese automobile manufacturer Nissan has showed a prototype of a self-cleaning paint that means cars may no longer need washing. The new nanotechnology paint has demonstrated to repel water, oil and other dirt the environment can throw at a car. The engineers have gone far. The paint is called Ultra-Ever Dry and uses a process that has been called nanopatterning.  This coats the surface of something with tiny bumps and grooves and has stopped water and oil from sticking to it. Nissan said the paint has "responded well" to many weather conditions, including cold, rain, sleet and snow. The carmaker added that the engineers have been testing the paint in the near future to see how close they can get to a product ready for market. "We have committed to addressing everyday problems our customers face and will have been always considering testing exciting, cutting-edge technology like this incredible coating application.
