What oil did you use? Sounds like a great process.

I used a mixture, mostly motor oil and some other oil. I still have some sulphur oil which can work well too

When I am hardening steel used motor oil is what I use.

I'm guessing that no one has tried Brownells Classic Rust Blue since I haven't got an answer to the original question.

I wanted to check my work area, here is what I have used as a cold blue touch up: Brownells Oxpho_Blue creme formula and
recommend it.

I was looking at rust blues, but for really small things, minor scratches, Mosin spike bayonets, swivels, and the like, I prefer Van's Instant Blue. Because of how it goes on I'm able to match the exiting blue without issue, I can even bleed it so it blends into troublesome areas. A 4oz bottle lasts me years... wish there were smaller bottles.

I've been meaning to try oil blacking, I've heard that really well used old engine oil works particularly well...

I've been thinking of trying hot cod liver oil bluing too, I believe that's the system used by Colt in the 1850's.
