Get a spray bomb primer and prime the bare metal. Choose a color primer that's closest to what the rest of the car is (i.e. a black primer for a dark colored car). After it fully dries (per label instructions for that particular primer), lightly sand it with a 400 or so to blend the surface to the rest of the substrate. You'll then be good to go with your painting.



I do have a bottle of Picklex 20 rust converter/metal prep which I could brush onto those spots, I might go that route.
