What to do about car rust?

Question

I bought a used truck and it has a few spots that have rust bubbling under the paint.  The wheel well is most prominent.  What should I do to eliminate the rust and keep it from coming back.  It is a work truck, so the final result doesn't need to be perfect, but should look decent; I'm not looking for professional solutions.

Sand off what you can. Then spray Rust Reformer ($8) on it, prime it ($5) and paint it($8).

So we have a bare metal surface to work on but before we do that we want to grab our rubbing alcohol

Sand the paint and rust down to bare metal.  Etch the metal with acid.  Neutralize.  Paint with Rustoleum primer and Rustoleum gloss finish paint.

The only way to completely repair rusted panels is to remove all the metal that is rusted and replace it will fresh steel. If you do not get it all removed it will just come back.

You can slow it down with angle grinder, grind down as much as possible, seal, fill, paint....  Only real solution is to cut it out completely and replace metal with metal.
