Has anyone tried etching anodized aluminum yet? I know Jay has demonstrated this at <2.0W (http://jtechphotonics.com/?p=2687), but I can’t make a mark even at 1.7A (>2.0W).

Perhaps my surface is too reflective. I’ve tried masking it with blue painters tape, did not work.

Next I am spray painting it with flat black and I will try again.
