Champion H10

I decided to use the suggestion of applying gun bluing to the H10 plugs I have. I have a set of rebuilt beer bottle plugs that had a grey color to the body. Wire wheeled it. then cleaned it with the special detergent that came with the bluing and applied the bluing. Waited about 40 seconds and washed it off. Looks much better than I thought it would. I tried an H11 plug that is cad plated. Same process and it looks just the same. Look great. I'm very happy with how this helpful suggestion is working. Thanks...
