Patina's and metallic coatings - Gun Blue - Gun Metal Blue

     This formula works on steel and steel alloys to form various shades of colors ranging from blue to black. The finish is similar in appearance to the results of a traditional hot bluing process, but is done at room temperature. Beautiful blue/black finishes can be created by anyone, safely at room temperature. Simply spray or immerse parts in the Gun Metal Blue solution and watch the finish begin to darken. The process can be stopped at any time by removing the part and rinsing with water. This allows the user to create many different colors along the blue-black range in a matter of seconds.
