How big are this rust areas? Small like a dime? Quarter? Larger?
There are a couple of ways to go about this. Everything from sanding and bondo to just covering it over with Diamond plate (I've got a buddy who that's all he would do...)

you will need a cut off wheel tool . you cut out all the rusted metal . then get some galvanized sheet metal and make a patch to fit. using a rivet tool/drill install rivets to hold in place. then use fiberglass reinforced bondo to cover the area. grind down so you get is level / kinda smooth. then use regular bondo to get the surface very smooth no pin holes. then prime/paint.
with rust coming thru the rocker you will have a good amount of metal to be replaced probably a 4 in X 12 inch section ...

Your best bet is to cut out the rusted material, cut a patch of sheet metal the same size and weld it in. You then grind down the welds and finish with as little bondo as possible. A good body man can do it without using any bondo. Then epoxy prime and paint.
A quick fix is to grind the spot a bit, dent it in a little and fill it with short strand fiberglass, sand, prime and paint....
Depends on how long you want it to last
