Ted S posted:If additives in Red n Tacky do attack bronze, then I wouldn't use it in a model train. What was it originally marketed for, what kind of materials? So many of my locos have nylon gears, I've been using Labelle 106 & 107 for years. Also Mobil 1 5W30 synthetic for oil, and occasionally Lubriplate or the gooey black Molybdenum (moly) grease on old-school postwar with all-metal gears.
Doesn’t black moly grease (Molybdenum disulfide?) also contain sulfur, or am I confused? Never was very good in chemistry class...
