Usually sheet metal went through a hot dip process. It cleaned, etched and lightly coated the metal. Casting were aged by time in process, cast at the Rouge, stockpiled, shipped as scheduled, stored at the tractor plant then machined. Castings too were run through a hot dip process, coated inside and out in the case of drive train housings.
