First make sure you can paint the object correctly. Some paints and rust-inhibitor paints want the steel to be rust-free. Other paints allow there to be some rust present.

You get superior results when you can paint like this. I like to paint steel with a spray gun when I can. It takes some extra time to set up to prevent over-rust paint spray, but in the long run it can be a time saver.
