What kind of laser did you have access to?
I don't. Colorado Laser Engraving has more than one. I didn't ask how many but he did say he used one for items with powder coat and a different one for bare metal. He said both plates the laser engraves a couple thousandths deep into the metal. If the plate burned and the powder coat burned, the etching would still be visible.
I mailed mine to him. I just happened to be in town so I picked them up. I'm sure he would return if you provided a self addressed postage paid envelope.
