On a different note...
I've been looking into doing the Medeco lock face and bezel in black. I did a test using the same powder coat I use and it came out ok. Had to mask the hell out of it though. I can order black from Medeco but they are special order at 4-5 weeks. The price just adds a couple of bucks. Just thinking out loud because having something shiny attracts attention. Here is the Medeco black and then my powder coat black. View attachment 1160664View attachment 1160665
I think you should go with black if you have future orders but wouldn't bother powder coating what you have on hand now.
