Be sure to clean that WD with an aggressive cleaner before you start grinding/sanding. That "Penetrating Oil" will soak in and give you fits when its time to paint.
i plan on using some castrol superclean straight up and a scrub brush before i use my buddies blaster to strip the rust and paint away, then rinse thoroughly with hot water and let it dry in the west texas sun for a day. the superclean stuff works great, but if you dont use rubber gloves it will strip a layer of skin of your hands. dont use it on anything aluminum since it is caustic and will start to eat away and discolor the metal.
