I'm trying to find some paint that would be suitable to repaint my large range cooked on the outside. The doors have began to rust. I'm not sure of what paint I would need to give the best finish. I have someone who will Cary out the work for me and has a kiln where he bakes the paint on but asked me to source my own paint for the cooker. Do you sell anything that would be suitable? Im looking for a gloss copper colour
