Rust and contaminant Removal

Just a thought, but as we have seen rust removal using a fibre laser, has anyone tried using a normal flatbed laser like we are using here to try it out?
Our business one is a 130W cabinet style unit and am game to give it a try once we get back next week.
I know it will be tricky because of focal points etc and 3D surfaces but it might be OK for the flatter objects and panels.

Anyone had a go at doing this?
