Chuck is right, but pits can also be filled.. JB Weld is one suggestion. It can be sanded perfectly smooth & painted over. You can also try using some auto-body spot filler, though I don't know how tough that is.
If the rust pits are deep, you can use muriatic acid to clean the rust out of the pitting before you fill & coat. Make sure to follow-up any muriatic use with some phosphoric acid.. else it's going to flash-rust like mad. If you don't have a bottle of it, RC Cola is a cheap & available source of phosphoric.. yes, it's low concentration, but it's enough to do the job.
