Wondered how well that stuff works for a project where a knife blade has some kind of krinkle paint or finish on it. I want polished steel then make a forced patina. But the finish has to go first. Anyone here ever use mustard on bare steel to create a patina? I can see a cool frame with that trick then BLO to retain the patina. I know, I'm not quite right. But this little world I live in, they know me and like me. Strange eh? Be Well, Short Stuff.
