Anyone ever used nu-blu gun finish?

[CATI1835]

Going to rehabilitate some magazines and associated parts, followers, floorplates, etc. This stuff looks like it might be what I am looking for. Anyone have any experience with it? I am not doing a whole gun and do not want to hot blue.

I have never personally used it but have read many mixed reviews. Some LOVE IT while others say it hasn't been any better than the other Blues. Sorry I can not be of more help.

The two best cold blues I've used (not that they last all that long) are the Birchwood Casey Perma-blue and the Brownell's Oxpho Blue paste. Sometimes one works better on a particular gun than the other. It's just trial and error to see which one takes better to a particular steel.

Never used Nu-Blu

Another vote for Brownells OXPHO-BLUE. Haven't used Nu-Blue but have used OXPHO-BLUE with, what I think, are great results ( for a cold blue) for several years. This Israeli Army surplus Hi-Power was a mess on the exterior, and after stripping, sanding, etc., etc. I gave it 3 applications of liquid OXPHO-BLUE. For a shooter it's pretty nice

Another product that I've had good luck with is Birchwood-Casey Brass Black. Abrade the surface (400-600 grit paper is good), degrease with Acetone (I use Goof-Off) and apply Brass Black.

It will darken immediately on most metal surfaces. If there's some residual oils, it'll take a bit longer and more applications with a cotton ball or Q-Tip.

Let it darken for 1-2 minutes and saturate the area with oil (to stop the process). Repeat as necessary.

A quick aside if you will: Kalifornia has been quietly banning gun chemicals for several years. Calls into Brownells for many Birchwood-Casey and other products into the State have been an exercise in futility.

A product that I have been using for several years to clean, preserve and protect is Zep Stainless Steel Polish. It's offered at Loews and is in a spray can. It's petroleum-based and has some powerful cleaning agents in it. Thus far, I have trusted it on all of my firearms. It cleans like nobody's business and better yet, it removes rust and corrosion.

On crusty/rusty guns, I use it with Copper Wool (coarseness depends on the job) for removing rust and exposing the metal underneath.

Sorry about the long-winded post. I'll try this stuff. It looks promising.

Cheers!

The only remarks I have is be very careful with that propane torch. Anything soldered like barrel ribs and whatnot can be melted free quickly. The Arizona Sun or a good heat gun is all I would recommend. I've had good luck with Birchwood Casey Blue & Rust Remover over the whole piece. Then the entire piece matches when blued.
