Who needs that? ;-) It *does* seem to last longer than dry lubricants (talc/teflon,etc.) This is because the grease will soak into the leather/buckskin making it next to impossible to clean off. This is not a good thing. While MPL is nifty stuff with many uses in other areas of pianos, talc,powered teflon, dry-teflon spray, soapstone and the like make more sense in friction critical areas like the knuckle,jack tip contact area. Oh yeah, Protec works admirably here,too. The liquids evaporate quickly leaving no residue, just the clean dry lubricant. Paul E.
