Cold blueing recomendations

I am wanting some opinions on cold blue. I have used birchwood/casey and didn't like it, I want more of a black finish. It is going to be on a a complete job on a freinds muzzle loader.

Search down in this area a bit, and you'll find a recent series of messages on cold-bluing. They'll probablyl answer your questions. (Generally speaking, most of the folks here don't like to use cold-bluing for a complete gun... I've done it with good success, but uniformity of bluing is a problem. Also, I found Birchwood-Casey cold blue to be one of the most "temporary" of cold blues, while several brands from Brownells do quite well.)

You might consider Gun-kote or one of the other similar spray on/bake on finishes for your fiend's BP gun. Much, much more durable. You may have to create a "light" box to do the baking, however.

Can u give me more info on a light box? My wife said no way on the use of the stove.:D

I've not seen it done -- only heard of it -- but heard/read of it on this part of the Forum.

You'll have to hope that others here can give you more info.

Your wife is wise. Gun-Kote apparently makes a great finish, but stinks like SHI... urh. Its pretty bad, while its cooking.

Some coatings give off flammable vapors while cooking. If the relay clicking to regulate the oven heater has exposed contacts (or any spark is around) you can cause an explosion in the house. After that happens, you will be living in that unhappy land in hawaai called Lakanookey.

Brownell's sells a cold blue called Oxpho, that according to them is one of the more durable of the cold blues on the market.

''Formula 44/40'' and ''Oxpho'' are both quite good .... and, ''Blue Wonder'' is reckoned to work very well. I have some but have yet to evaluate it.

It is possible to use more than one cold blue on a job .. and the very most critical aspect is preparation, in particular TOTAL degreasing ... and keeping it that way.

Best way to try for first time is to practice on some bright steel or an old gun .. experimentation pays off handsomely.

Brownells oxpo blue worked great, I used vey fine steel wool to apply it and I got 0 streaks, letting it sit overnight in oil. Any thing I should do to it befor I clean it and clp it, also will break free powder blast hurt my nice bluing job?

Glad you got a pleasing result .... now just wipe with CLP cloth ... and treat it with some care. That finish will wear fast with abrasion .. well, friction on clothing, holsters, that kinda thing.

If tho it is treated well, it can last a long time ... just remember it is a very thin layer.

Is there a more durable cold blue out there, also once I cleaned it up it has some streaks on it today.:(

None of the cold blues are especially durable -- but you can improve both "cover"/streakiness and durability, but continuing to put on thin coats. Polish it betwee coats with steel wool. You can apply it with steel wool, too, but keep the steel wool ALMOST dry. I prefer cotton cleaning squares...

Oxpho-Blue goes on great with cleaning patches that are almost dry. (Be sure to pour out a portion of the chemical into a container before using it. ITs real easy to contaminate and kill the chemicals. a small cup or saucer, lined in Saran Wrap or aluminum foil should be OK. Steel wool, as noted -- but don't let anything directly touch the stuff still in the bottle.)
