I went to halfords and bought a spray can of clear spray paint that you'd use as the top coat. It held up fine. Obviously it rusts a bit underneath and discolours over time, so you need to keep an eye on it. But mine is an old 531 track frame that's fairly tough. I wouldn't ever raw anything that's made from decent tubing unless you want to have to baby it.
IMO although clear coating takes a bit more work at the start, it is easier than having to constantly wipe or oil it to make sure you avoid rust marks on your clothes.
