Depends if it is California surface rust or back east rot rust. Surface rust: Can't see it from the drivers seat. Rot rust: Power wash or sandblast and then bedliner spray or undercoat. But don't blast thru it. I never would feel good about just Por 15 right on old virgin rot rust. Maybe that's OK though.
