Clean off flaky rust/lifting paint then prep and ospho. If not flaky, sand/wire brush the rust and then use one of the rust converting primers.

Believe it or not, you don't even need to remove the old rust.
I've used this product on many things around the house and the rust never returns.

Seriously, it works.

Also seriously, don't get it on your hands.

I just finished painting a 25 year old boat trailer that was showing a ton of surface rust. I sanded everything and cleaned well wuth Acetone. I then applied a coat of Eastwood rust inhibitor, then a marine paint. Not sure how well it will hold up long-term.
