So, I got a new shipment of anodized from my supplier and noticed the new parts had a little difference appearance or sheen - hard to describe. Still anodized aluminum - just what I ordered. Did my standard Cermark/laser process and ........... well, you've got to love this business or it will drive you crazy. Well, got to run now and figure out how to mark the new material with a good, dark, consistent, repeatable mark - like I had with the last batch.
To the laser, Bat Man!
