testcase;
The "dirty little secret" of firearms refinishing is that most of the time, when you see "blued stainless" it's one of two processes;
Plating with iron, then traditional caustic salt blueing (sometimes both done in the same bath), or a rather thin black phosphate finish that's not very durable.
I think the "quickie do it yourself" stainless bluing products are a phosphate finish.
I could be wrong... been a while since I did any blueing or extensive metal finishing lately...
