After years of hearing drivers complain about scratches(划痕)on their cars, Japan's Nissan Motor Company has officially announced the next big thing--a paint that not only resists scratches and scrapes, but actually repairs itself within a few days．
The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin(弹性树脂)that is able to heal minor(较小的)marks caused by car wash equipment, parking lot encounters, road debris(石头碎片)or even on-purpose destruction．
The automaker admits its results vary depending on the temperature and the depth of the damage, but adds “this is the only paint like it in the world, and tests prove it works．”
Minor scratches, the most common type, are said to slowly fade over about a week．And once they're gone, there is no trace(痕迹)that they were ever there．
The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period．
Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents．
But the complete auto-healing won't come without scratching your wallet．The vehicle maker notes the special paint adds about ＄ 100 US to the price of a car．
It plans to use its new chemical mixture only on its X-Trail SUVs in Japan for now, as it looks for a more widespread presentation．And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores as well．
