Good blueing, hard to get it right.
August 1, 2011
I bought this bottle to touch up some blueing on an old airgun. That did the trick very nicely, and worked as expected. Then I started playing around with it, just like a kid with a chemistry set... I started blueing some of my knives. Although it works well, it's hard to get it right, to get the blue even. So, touching up those spots of worn of blueing is OK, but I wouldn't try doing a whole gun with it.
