Ray, I think there was a restriction on the link not allowing it to be copied or shared.
I was able to see it a couple of hours ago, it showed fantastic clean up of rust and other build up on a bolt, a fan clutch I believe and even a engine block. One concern I would have that it would remove parent metal of for example a sealing face. If it only removes build up and leaves the parent metal untouched then it would indeed be a game changer.
In my business on turbogenerators (large steam and gas turbine rotors) we used sub contractors that used walnut shells, glass beat etc. to remove build up on turbine rotor blades. It often resulted in damage to leading edges of the turbine blades (bending the very thin leading edges) this then required extensive and costly repairs by qualified OEM technishions. This new laser technology would be a great improvement provided that parent metal is not touched during the cleanup. The write up in the link mentioned that patents are pending and that the link was not to be copied (perhaps that is why the link now is broken).
