Brilliance laser inks and other related products

I need to get some plaques for trophies and thought to my self, “Self, maybe you could use the laser cutter!” I just need to etch 2" x 4" metal plates (don’t care what metal - heck, I could probably use glass).

Does anyone have experience with this stuff (or products like it):

Are the other methods I should consider?

Thanks,
Cliff

You can get very durable results by etching anodized aluminum. You can buy dog tags and nameplate sized pieces with colored anodizing, and the laser will etch it away leaving white lettering.
