Pic of the application? Typically, OBCS grease as well as aluminum complex has better washout and water resistance than lithium. WD-40 Specialist multi-purpose grease, Red Line CV-2 and Lucas Marine Grease are OBCS, almost all Schaeffer’s is aluminum complex.
RP-342/Cosmoline will not let off metal easily. I had some on a battery hold down as overspray. A few years later, I had to use brake cleaner and razor blades to get it off. It works best on non-mechanical parts.
