sanded slinger
I figured engine oil would do, as it lives there forever - I was assuming it's the 'dry rip' that we're trying to protect against - when not separated from metal by a decent grease, and left under some pressure, rubber will bond to metal fairly quickly - like in days, usually when new. Grease has enough viscosity to prevent. If it's not critical, Redline CV2 it is!
Sand the surface . . .as in to 'plow' the oil back into the engine against the seal surface? Nope, hadn't heard that one yet. Using what? I'm sure I don't want to go more than a 250 cloth on that . . .even that may be too much?
