I'm having the slide of my 1911 refinished with nickel boron, and I have an idea to make it more of a personalized, custom look. I was thinking I use a dremel to make an engraving and then drop it in the parkerizing solution to blacken up (and protect, of course) metal that I took off. But then, I'm not certain how it would react to the nickel boron finish. I have heard that it wouldn't have any reaction, or that the phosphate would simply rub off, but I have no reliable sources on this. Any experience or better ideas to accomplish the same thing?
