Spray with Insta-rust (you can see the copper color on the back of the petals) then while it is still wet burn it off with a torch. It will make a white residue first then turn dark. Later when it cools and is dry it will be yellow. If you don't seal it will go ahead and rust the next day. The trouble is when you seal it, it turns dark and stays that way. I have burned the sealer off with a torch and sprayed again with insta-rust while it was still hot and when it cools and dries it will be yellow again. I just can't find a way to keep it. The only thing about waxing it directly is that it will rub off. It seems to have something to do with the copper plate left by the Insta-rust and the heat. You can seal the copper plate color left by the Insta-rust and it will stay but not the yellow.
All this patina stuff is new to me and steel is hard to get very many different colors on. Its so hard to duplicate outcomes when you aren't using new sheet metal and your base may not be exactly the same each time.
