It's tough stuff if applied properly and cured as Rhino mentioned. I've hit is with a 40 watt laser and like the results, Duracoat just burns right off but Alumahyde stays put with some discoloration. I'm working on creating a digital camo pattern and using it as the base, with the laser creating different shades based on the power level.
At full power on OD green Alumahyde, you get the subdued look anywhere the laser hits it, just like the green subdued flags on U.S. Military uniforms. Looks pretty sweet.
