Decided to replace this video with this interesting video on Hydrographics as Drew had already posted the Robocop one.

bit Late mate, already posted it up

the hydrographics look brilliant , we have used them to cover our guns at the shooting range for years..

but they tend to chip and mark easily when knocked..

why he covered a dented tank at the start baffles me. you would have thought he would have knocked it out first..
