Chris - take your frame to somewhere like Armourtex (where they have shot blasting on site). Last time I had a rusty nail they shot blasted the worst area to check the extent of the rust. It cost me nothing and you'll know whether to bother.
It's pretty thin 531 so i'm not letting anyone near it with the shotblasting gear. It's probably ok anyway, just want to see what people consider rusty.
