My local hardware store carries a spray paint especially made to withstand high heats i.e. wood stoves. I just sanded down the rusty spots on my wood cook stove, sprayed the whole thing and it looks and works great. The first 2 times I fired it up it smelled somewhat, but after that the paint was set/cured and no smell. cleans like a breeze. I also used it on my big wood heating stove with excellent results. It also prevents rust from coming back and/or starting anew.
