You have some Fabrication to do, but for surface rust, I Absolutely Love Rustoleums Rust Reformer. It's in a small white rectangle bottle. I grind down to metal, then apply several coats and then paint. Did an old ford 2-N, that had NO paint on it, 20 yrs ago. The new paint is faded, it sits out, but, the rust that was coated, has not returned....AWESOME Product.
