Best cold blue avaiable
Gentlemen,
What in your opinion is the most durable cold blue? Mostly for shotgun slides and barrels

Mark Lee's Express blue carried by Brownellshttp://www.brownells.com/aspx/NS/store/ ... %20BLUE%20.But you well need a tank capable of boiling water(Hot blue tank-stainless) for the plugged barrel actions.Baldur Buffer with SS wirewheel will speed up the carding.This solution used by many top custom bolt rifle builders.

Re: Best cold blue avaiable
some will disagree with me and everyone has different results. i tried oxpho blue and it's very easy to apply and does a good job. you dont even have to remove oil from the surface to apply it. my only complaint was that it didnt give me a dark enough blue as it was more of a charcoal color. i tried blue wonder and the color came out almost like a factory blue job for me anyway. even did a cresent buttplate with it and it looks real close to a hot blue job.Paul Jenkins wrote:Gentlemen,

I like Oxpho above all others - leaves a very durable and dark coating. It is actually a commercial blackening product for industrial use, although Brownell's sells it for the tough jobs. It's especially good on bead blasted finishes but for a polished finish, I think it's best to have the steel chemically clean as oil does slow the reaction.
Even though it's a cold blue, it also helps to warm the steel a little and immerse it in the solution. It works quite well on pistols and small pieces to boil the parts in water then go straight to bluing. I buy Oxpho by the gallon and cut it with a gallon of distilled water, then I pour the mixture in a tub and immerse the piece. This will produce a smut residue that will drop out of solution but the mix will keep and work for a very long time before it needs replenishing.

I’m not a big fan of cold blues, kind of like repainting your car with a spray can, it can be done, and some can do a good job, but it’s not really the way to go.
Most cause more problems than they are worth i.e... After rust. And even the best seem to turn brown after a few years.
There seems to be two basic formulations for cold blues; Copper Sulphate and selenous acid, even the new “Revolutionaryâ€
