Thanks, got one of those "some day" projects in the works that would be best with a nice rust blue, nice to hear a good report. I also degrase before browning with the stuff but perhaps not so thoroughly. Word is that a powerful detergent was added to the basic solution and I don't want to test it's limits. Mainly I don't have to take all those skin oil from handling precautions that are in the old gunsmithing books.

Which explains a lot.
