I use Vans gun blue which works great.? The key is to make sure that you clean the metal prior to bluing.? I use ultrasonic cleaner and acetone for cleaning metal and to avoid touching the metal I wear gloves.? I also saturate the metal surface with the bluing keeping it wet for at least 3-5 minutes, I rinse the parts and dry well after rinsing then soak the blued parts in an oil bath for no less than 24 hours.? If you do it right you can have a nice protective coating that lasts for a long time. Have A Great Day?? Tracy Ranson On Mon, Mar 11, 2024 at 10:10?AM Bruce J <bruce.desertrat@...> wrote:
