Zinc coating for diode laser etching glass tile. Water clean up. High contrast

After trying every type of paint used on youtube vid s for diode laser etching tile and glass and dozens not shown on you tube, I found a spray on compound that works better for me. Rustoleum, 7585838 cold galvanizing compound. I did my glass and tile tests at 50 power and 1000mm per minuet. I found that I could clean off the compound with warm water and a Brillo pad steel wool. So no more harsh chemicals to clean of the spray paint I used before. I have not tried this stuff on other materials yet but it could be interesting to see if it will work with any metals.
