Bummer is it give a white translucent coating or matte finish. Plus it can't handle high abrasion or high human hand contact. Looks killer, but wouldn't be good in high luster or high handled areas. Pretty sweet technology, if they could get it to be a clear coat, I could see this being applied to the automotive industry too. It would be awesome not to have to wash your car!
