I have had pretty good luck with using a wire brush on a angle grinder and then follow with a "Rust Reformer" made by Rust-Oleum ( RustOleum.com ). Can find it at most auto parts store. The rust reformer converts the rust into some thing else (forming a black primer). I have used multiple paints onto this primer and they all seem to hold well.
Good luck with your projects.
