IIRC almost from start all Maytag WW were designed to be rebuilt/refinished. Dealers were encouraged to take machines that were traded in or whatever, give them appropriate treatment, mark them up and sell them on.
My Maytag service manual for dealers gives extensive and exhaustive details on doing such restoration/repair/rebuild work on range of models. Of course Maytag sold paints, spray guns, parts, kits and whatever else a dealer could possibly need for such work.
Year or so ago now there was an auction from an old hardware store that had shelves full of NOS Maytag WW bits. Rollers, paint, etc... lots of goodies.
A member did a full restore job on his Maytag 90.
