I have a Super Nova shotgun that I want to individualize by adding some color to it. However, I really don't want to spend the money for the various spray paints and coatings that are specific to gun refinishing. So, I am wondering if any one has used regular enamel spray paint on a gun. I adding color to the forearm, end cap for the extended magazine tube, the mag tube to barrel brace, and some other small parts. Of all these, the forearm would get the most wear. I was thinking of spraying clear coat over the color coat. Any thoughts, and/or personal experience with using regular spray paint on a gun?
