laser cleaning versus sandblasting

[Woozy Song]

Has anybody tried laser cleaning for a classic car shell, that has been
overcome with 'patina'?
I also wonder are those things restricted, having hundreds of watts of
power, that could do a lot of damage in the wrong hands.

The laser is tuned to whatever you don't want to remain;
paint, rust, oil etc. Laser ablation vaporizes the crud
without harming the substrate.
