Step One: Tried buffing with Flitz. Nothing much happened. Step Two: Tried buffing on my bench buffing wheels with super fine grit. I looked a little better, BUT the USFA matte finish is very hard and seemed to be resisting. Step Three: Tried medium buffing compound. This was too much and went down to white metal. Now I was in trouble. Step Four: buffed all the old blue off with medium and polished with fine on my other buffing wheel. Now it looked like it was nickel plated. Step Five: Degreased with MEK, the fumes made me see Elvis. Step Six: Heated to around 200 degree with my big heat gun and applied MARK LEE Express Blue with cotton patches. It is now rusty red. Step Seven: Place cylinder in boiling water for a few minutes. The red rust is now black. Step Eight: Card off rust with fine steel wool. ( degreased steel wool with denatured alcohol) Kept repeating steps 5, 6, 7 and 8.... Step Nine: The next day the sunlight showed that the base color of the blue was red. Probably from using my well water. Started all over again but used rain water. Soaked with oil. It is OK and much more glossy than the matte finish. But it will never be as tough as the matte finish.
