Neolube is great stuff. I've painted locomotive wheels with it. But you can pay less than P-B-L wants for it. Look around.

Careful here......the Neolube contains graphite as it's lubricating medium. On insulated drivers it can "bridge" the insulation band and cause them to then be conductive. . . with the corresponding short across the driver set......! Don't ask how I know this......!
