Nissan Creates New Paint that Repairs Scratches Automatically

Not that we’re recommending that you put it to the test, but Nissan Motor Co. has developed a new exterior paint that will automatically repair itself if it gets scratched. Reportedly finding its first North American application with the new 2008 Infiniti EX35 when it gets launched here in late December, “fluid finish” technology is set to revolutionize the automotive paint industry.

The technology, originally introduced under the name “scratch guard” in 2005, is currently being used on a Japanese-market X-Trail.

So how does it work? Like most new innovations, it sounds a lot simpler than it probably is. The trick comes down to a unique clearcoat layer that contains an elastic resin. The resin retains fluidity for about three years into the car’s life, allowing the coating to flow back into shape, thus erasing minor scratches.

According to Nissan, the special paint takes anywhere from a few hours to a few days to fully remove a scratch, the variables due to air temperature levels and the severity of damage done to the affected area.

Of note, the upcoming EX35 will compete in the fast growing compact luxury segment currently occupied by Acura’s RDX, BMW’s X3 and Land Rover’s LR2. Audi and Volvo are expected to enter this segment soon, while premium compact SUVs from Lexus, Mercedes-Benz and Saab are rumored. Volkswagen, considered by many to be an entry-level premium brand, will offer its new Tiguan in this segment next year.

None offer self-repairing paint, however, although as innovative as this new technology appears it will be unlikely to affect overall sales dramatically.

The EX will offer a camera-based “lane departure prevention” system, mind you, which combined with other safety features and what is expected to be a dynamic driving experience, will no doubt make the stylish EX35 a formidable player.
