Perfect for a golfer looking for a more rugged look than a Black Oxide, and more of Gun Blue look. Every Gun Metal Finish includes removal of minor dents and scratches, finish application by hand, so results will vary and color fills up to four colors. This classic Gun Metal Finish is recommended for the golfer who wants to restore their Carbon Steel putter without any final finish. This putter will require maintenance to avoid rusting on carbon, similar to the oil can finish. Keep it dry and well oiled to prevent rusting.
