The " Blue Wonder " stuff works fairly well and is usable for touchup , will only blue the scratches .
Not perfect , but sure beats stripping and reblueing ...
You need to use their cleaner first , and you will need a torch or heatgun .

Some times you can work absolute wonders with felt tip markers! then lightly oil.

If you use one of the so called "cold blues" like Oxpho, Birchwood Casey, etc make sure to heat the metal up before you apply the blue. I use scalding hot water, on small parts you can boil the water and parts then dip them in the blue solution. Heating the part will expand the substrate opening the pores so the chemical will penetrate deeper... or in other words it works so much better to heat the metal first.

Did you kick the guy who kicked them to the ground?

How about naturally bluing with heat? Is that an acceptable practise among gun owners? We do it with our metal samples for a certain analysis.

That's not how it works. Metal has no pores. Bluing will not penetrate. It stays on the surface.

I didn't kick the gal who kicked my rifles because she's a girl and violence in a gun-laden environment didn't seem like a good idea at the time 
Back to the issue, I intend to give Blue Wonder a try. The hot bluing techniques based on lye and ammonia nitrate are too dangerous to even think about.
Unless there's a less caustic/toxic way to hot blue.
Well, is there?

Don't think that you can do without the caustic (an alkali pH is what we do to get the stable black oxide in boilers at 300C, and two tonnes per second flow rates), but the attached link is close to what I recall from reading a bunch of old gun books an age ago.

I've pulled sodium/potassium nitrates out of soluble liquid fertilisers, and it's not that hard.

thanks, I might actually try this

Try Van's gun blue first before concocting nasty home brews...no mess, durable, and pretty cold blue. Blends really nice
