I'd like to extend the Protek discussion with questions. Specifically: - are MPL-1 and 'VJ' lube interchangeable in various usages? - at what times is MPL-1 used instead of 'VJ' lube? - at what times is VJ lube superior to MPL-1, if ever? Play with these variations as much as you wish. The question is, should we be carrying both when *one* will suffice? Background for the unitiated: 'VJ' is an abbreviation for Vic Jackson. In the 'old' days, it was common to use mutton tallow in certain situations in pianos, along with various greases and talc. Mutton tallow became progressively harder to find. Vic Jackson is credited with creating this homogenous mixture -- what I would consider a super-saturated solution -- of petroleum jelly, talc, and a trace amount of anhydrous lanolin. Loosely explained, VJ lube can be applied to unlike surfaces (metal to metal, wood to metal, felt/cloth to wood, and other combinations) and the appropriate lubricating agent within the mixture will "kick in". Thanks/Jim Harvey, RPT
