You know I recently saw this laser rust blaster on video the other day! For the life of me I can't find the video to post up, but was it amazing! It was pure ecstasy watching all that rust just melt off when the laser pulsed on the different surfaces. Pretty sure that it's industrial use though so for us poor consumers, we'll probably need to find an alternative.

I've seen that video too - high powered laser and fast rust removal.
