Nissan paint that doesn't scratch

There is a story on the Pysorg.com site that announced a new non scratch paint form Nissan.

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

Now I can almost imagine a resin that would do that but there is always a trade off as Dom Palon keeps reminding me. What would a resin like this trade away, color life, fade resistance, how well would it stand up to chemicals. There is also one other little thing about the story they show a scratched hood when you photoshop a photo you can usually tell what the original photo was in this case it was a Chrysler Town and Country. We'll wait and see.
