Those pmags are about as good as you'll get, a nice tan/sand color is the goal and it looks like you got it!

For metals, especially dark metal, you'll probably find that higher frequency and higher speed will give you pretty nice results, about like the suppressor you showed.

So far so good!

I did get white engrave on some suppressors IMG_20200505_175618.jpg, holographics and in my CZ Sp01 magazines IMG_20200505_175531.jpg, with very low power, I didn't want to mark the metal deeply. I will have to do a lots of trials and errors to get acceptable results.


I hadn't thought about applying something unfocused. I will try tomorrow in the pmags.
