In my experience with browning or blueing, one can get a very wide variety of results, depending on what is desired. By using high humidity and multiple applications between carding, a coarse grained finish or even pitting can be achieved. With diluted agent, less humidity, and careful carding between applications a light reddish brown, almost transparent finish can be achieved. I’m not as sold on browning for flintlock era American guns as I was in 1978. Now it’s part of the simulated aging process for me. I often get it well browned then take most of it off, and perhaps tint it with an application of quick blueing agent, then highlight wear areas using pumice and a wet polish.
I recommend this product because it wasn’t tricky to apply like some that require the “one direction, light coat, do not overlap brush strokes” and so on. I am getting uniform color and texture.
