Would someone tell me what is wrong with Art's belgium blue. I asked this a week or so ago ad no one answered.

I have had good luck with it. Is is that it is not "traditional rust bluing"?

Has anyone tried to finish damascus barrels with it?

I really would like the input of the forum members...I know so little... compare to most. (Okay that may be a little thick!)

Thanks for your input

Jerry
