again though ... sanding the rust off is the correct answer

Search "Rust Converter Tannic acid 2-Butoxyethanol". With that, the preparation is just to get the flakey/loose bits off (sanding, wire-brushing). The rust can remain, as the rust converter results in a black polymer that's stable enough base to be primed / painted.
Upgrading to a galvalume primer is a tad more expensive, but the zinc in it will help if the railing is in a high-use/abuse environment (the "healing" from the scratch-through of the paint layers). I learned a lot about this when looking up specs for sheet steels coated for metal roof / gutter applications.
