Hi, I have belt buckles that I am trying to etch/mark/engrave on. they are of a zinc alloy. to save money and per advice from many others I used CRC Dry Moly Lube as an alternative to Cermark. I can see a slight etching, but not quite as noticeable as I would like. I have a basic and used 60 power and 300 speed, 2 runs.
does anyone have experience etching/marking/engraving on a zinc alloy metal? any tips for me?
