Thread: Cold Bluing.

Now I'm not a chemist by training - but the cold blueing Birchwood Casey product process is not painting on blue. Here's the blurb:

"The Birchwood Casey super blue for deep, blue-black finish penetrates hard steel instantly. The Casey super blue is double strength bluing solution designed for bluing highly polished steel parts and hardened steels containing nickel and chrome alloys."

Its visibly a chemical process as you work it across gun metal inch by inch - apparently a controlled oxidation of the metals similar to rust. Some earlier products were less effective but this last one very good. Does it work - and last - yes. Birchwood Casey Superblue an effective blue process from my experiences. I can't ask for more than that.. Give some a try Akaroa - or sometime I'll come over to Aka and do a rifle for you..
