John Freeman Protek can be purchased from any Piano supply house,i.e. Schaff, Pianotek, American, S.F. Supply. There are a couple of different types of Protek lubricants available. What you are looking for is the Protek CLP (center pin cleaning lubricant) The other is a grease type lubricant for wood-wood, wood-metal called Protek MPL (multipurpose lubricant) I have found that it works well on trapwork, much like VJ lube. I have found that Protek does not work as well for me for application of center pins. Unless they are just borderline. I almost always resize with alcohol/water instead. I mainly use protek for squeaky key bushings. Although I did use it on some squeaky korean knuckles. (I was out of teflon, and it was an emergency) It was only a temporary fix though. Did have to return a few months later to do the teflon/McLube combination. I have also found Protek to be of good use on the Pedal pins that have the Plastic mounting hardware. No disassembly and it gets rid of the squeaks. Mike Masters Masters Piano Service Lakewood, OH
