I used to use an angle grinder or have a spot sandblasted. Scott said to try a wire brush. I got the kind that mounts in an angle grinder and has the wires twisted into pigtails. It works like a charm. No muss, no fuss. You can treat any rust left, spot putty or bondo the depression, shoot with high-build primer, sand and paint. You can do this with small preval sprayers pretty well.
