Hi Roomage,
Where do you live? How old are you looking for? 1940s, 1950s etc.? Are you Looking for a specific color? Are you looking for multiples or one, Four draw or two draw? I know people that used white vinegar to stabilize rust. After it dries, lightly buff off flakes. Some then use a clear coat to keep from further rusting. The paint comes in spray or brush on with shines or matte finishes.
