Hot water Belgium bluing ?

[Ruff Hunter]

I've seen the results. They are much more blue that a proper rust bluing, which is closer to black in color. Not a bad look by any means, just not authentic for an American double.

We experimented with Several of the "Blue " products, 30 years ago. The end results are a dark blue not black. I have yet to see an original set of barrels that were produced in that color.
Stick with the newer commercial products that yield a true black finish. The preparation is 98 % of the finished job.
