I blue summer and winter in my shop. Humidity can be all over the place. I use milder solution if I think it will get away from me. I too prefer lots of applications of very mild solution to get a smooth luster, however, I have to adjust my solution to the rest of my life. I can't do a bunch of coats quickly.

I think all rust blues and all brownings tend toward plumb eventually. There is a slow conversion to some sort of equilibrium of Fe2O3 and Fe3O4 (or whatever the correct compositions are) or at least that is wha II think happens over long periods of time.

Different steel alloy has different colors. Some of the welds I have had done can be seen no matter how much I try to blend them. My favorite welder for Winchesters, however, gets it just right every time. I don't know how he does it, but legend has it that he collects coat hangers.
