Homebrew Hot Blueing

[Steinar]

Thanks Mike, I'm still alive and kicking Feeling better now after having a tumour removed, so it's back to the fun things in life

It seems like Duracoat is a product that is very popular now days. It's not bluing, but when I held a pistol with black Duracoat in my hands, I could swear it was..
Perhaps that's alternative to Blue Wonder.
