I got a bit more advice from another Coleman stove fellow: Phosphoric acid wash, which stops the rust from eating the metal. He recommends a brand called Ospho, although he said there are a lot of others out there. And for paint, he said Krylon or Rustoleum, just make sure to do several light coats instead of one heavy one
