I was trying to come up with a way to show a customer what his badge would look like on a black surface (think Glock). I had engraved on a 1911 slide for him recently.
I didn't have any scrap black finished aluminum, but plenty of plain. So I brushed a coat of flat black acrylic house paint on a scrap and after drying engraved it with my fiber.
Looked good and all is well. But I thought I'd play a bit as laser went through paint easy. So I painted a couple of coats on a scrap of plywood. And Dang if it didn't go through it just as easy as on the aluminum.
How about that? Well, not really a surprise, if it cut through layer on aluminum, it would do same on any other surface.

But the nifty thing in my mind, is that it is another way you can use your fiber on a surface that won't engrave, i.e., base wood remains untouched and unmarked.


But there is the engraving..
