This thread is a great place to start if you haven't seen it already:

The other thing that is not always mentioned to new guys is that if you are just honing out damaged areas, putting some decent pressure on the blade is acceptable, as are circular strokes. You have to remove a fixed amount of material, so anything that will get you to that goal is fair game. You just have to know where to stop the aggressive work and return to the smooth, even, light pressured passes.
