IF you wondering how i get the por15 to stay in only the rust pits.....i paint the area with por15, then come back next day and pass some 180 over it. It comes right off the "clean" metal but stays on the rust spots/pits. It seems to work ok, then i gave it two coats of epoxy primer and two coats of urethane primer.
