Bluing shotgun barrels with Black Oxide?

[Beach004]

I came across this site, and the product Black Oxide. I am starting to reblue shotguns and shotgun parts, on a very small scale. I don't have access to either slow rust or hot rust processes, so I have been doing cold bluing, with limited success; it's blotchy and sometimes doesn't "take" at all.
What about Black Oxide? Does it resemble a blued finish? The second coat, the sealant--does that remain on the gun, or is it wiped or rinsed off? If the barrel is polished well beforehand, will the blued finish be fairly glossy?
I ask, because there are a good many folks like me who are looking for a better cold bluing process, and hoping this might be it.
Thanks!

Your application is the primary use for our Black Oxide system. The penetrating sealer remains on the finish and helps protect it from the elements.
