Re: WD-40 rust prevention? Doors?
I have used motorcycle spray chain lube on several cars/trucks over the years with good results. The spray is designed to wick into small openings, then the light, volatile carrier evaporates leaving a thick greaselike coating inside. Just spray it into the back side of any body pinch welds or sheet meet skins like doors, hood lip, rocker panels and trunk/tailgate. The spray can comes with a tube to direct the spray right where you want it. There will be an odor but it goes away soon. Also, some clean up may be needed from any drips that make their way out of the drain holes in the doors or other body panels. Not a big deal.
