I just finished stripping the paint off of a CZ82. I used Stripeeze and 0000 steel wool and lots of elbow grease. After stripping I found that the metal on the slide had a really pebbled,dark surface. Maybe to help in the adherence of the paint. I did paint it as I felt that bluing that surface would not look very good. I am sure others have gone the bluing route but, I painted. It looks good.
