My son and I like to use a 3" or 4" wire wheel on a drill. They can get it down to the metal and remove most/all of the rust. It will look as good as new. Wear safety goggles for any flying rust or wires from the wheel!
Just take your time and go one section at a time until it is all done. It sure beats a hand held wire brush.
Then you can use the POR 15 and it will last alot longer before rusting.
