I had a small rust spot (about 1 inch in diameter) on my rear fender. I sanded it down to the bare metal and applied a coat of rustoleum. I plan to recoat this a few more times. It shows but I don't care about that. Is this likely to last?

If it's the 'good' Rustoleum primer and paint that's heavy on the fish oil, it will last for a few years before the rust comes back - a lot longer than if you did nothing.

There are several products (I forget there names) you can apply to rust these days that actually will permanently convert it into a paintable material without the need to remove it. Check the paint department for rust converters.
Or if you have sanded the rust off down to shiny bare metal then a wipe with Muratic acid (stuff for swimming pools) kills rust.
Either one done correctly should solve the rust problem unless new rust is allowed to start growing there.
I think you mean phosphoric acid, not Muratic acid. A product which comes to mind is Ospho, which is used to prevent/kill rust on bare metal surfaces prior to painting. I'm not trying to promote a particular company or product, however, view the Ospho site to get some info
