Weird question from a newbie. I was watching a video last night and the person had a compact 1911 with a parkerized finish. But, the markings on both sides of the slide were silver. My question is - can I do this myself by putting some paint on a rag, running it over the slide, and then wipe off the excess? Will doing this affect the parkerized finish on my 1911? Is there a certain type of paint to use?
