Episode 1 of Car Science on SPEED has a segment about car paint that would use nanotechnology to heal itself after scratches. To demonstrate, they had a segment where an angry girl "keys" the crap out of a douchebag's Porsche Boxster - with what looks like the flathead on a Wave! The shots weren't clear enough to ID the tool, but it looked a lot like a Wave, Charge, or Surge to me. I'll see if I can find the episode and screencap it.
