|Depending on initial steel, its treatment, and the paint, you might just have chips exposing an underlying primer or a protective coating on the steel. In that case, just clean it (a little paint thinner to wipe the area) and apply paint over it, but don't try to sand to bare metal.
If you actually have rusty pits, those call for gentle removal of the rust (I've been known to do this with a dental pic or a knife point so that I get only the pit, no surrounding good metal). Then fill the pit ... small ones may just need a thick-bodied rustproofing primer.
If these are really small chips, you can probably get by with the closest automotive touchup paint. These usually go on like fingernail polish. The match probably won't be perfect, nor perfectly smooth, but it will hide chips and probably not be very noticable.
For larger areas (scrapes, for example), you need to decide just how much you want to invest. It probably needs to be sprayed to get a good finish, and the color match must be very close to not be noticed.
