I know we have been down this road before.
I do not know how to search for old posts or I would do so.

The best I've used is the Brownells Oxpho blue (think thats the right one, its a blue liquid in a bottle). If you degrease the metal and warm it the cold blue takes better, even though I don't think the Brownells specifies either of those things.

I use a q-tip to apply it. I believe its not good for the solution to allow the used q-tip back in the unused stuff when doing extra treatments. I pour a little out in the cap, use it, then toss whatevers left over so as not to contaminate the good stuff in the bottle. You could also just use a brand new q-tip each time you dip, but I dont have to worry when putting some in the cap.

Isnt it amazing how many people post without reading the thread?

I've used the Blue Wonder products a couple times. They require the use of a small propane torch or some other method of heating to apply properly. It looks really good when you apply it, and you can match several different shades of blue depending on how much you apply, but the durability leaves a lot to be desired. I don't know if this is true with most cold blueing products, but I might have to try the Oxpho Blue that the others have recommended.

OTOH, for small blips/areas, I get a decent hide/blend with Numrich Arms Formula 44-40 Cold Blue (liquid), de-greasing & warming the metal first.

Oxpho-Blue gives a darker, richer blue than the 44/40 stuff. As others have said warm the metal first, and use a dremel or drill with a wire wheel to polish. 3 coats will give a good blue, but more will really make it shine.

Oxpho-blue in the gel (now they call it cream) is easiest to use for spot touch-up.
