Ken, "Prussian Blue" was used to mark bearing metal, like poured bearing in
an engine block. You then fitted the shaft and rotated it which would wipe
the blue off the high points highlighting them for hand scrapping. It's
sort of like blue grease as I remember. Alcohol based marker pens mark
stainless pretty well if it's not oily.
