Beautiful machine and truly one of a kind.

You can use some Corrosion X to treat all of the metal parts but of course it has a smell so you don't want to cover your garage floor with the over spray. It doesn't smell quite as strong as WD-40 though. I tested it on a piece of steel wool which I then bathed repeatedly in salt water. The piece on the right is untreated. I still have the sample sitting on my bench somewhere and it hasn't changed in over a year.
