Protek but CLP : yes, Prolube : no ! On key bushing excellent results against wear, but sometime stain the wood on older pianos (the marks goes with time but a long time - 1 year or so). I'd say the wear is dramatically reduced, have seen a evenly used vertical 5 years after treatment with not an ounce (500 gm !) of wear or play at the key, balance and front as well. Great use for the stuff, but I don't like the look the wood takes for a moment when applied. For center pins, I'd not trust the stuff too much unless very little friction is to be corrected. I even experiment the treated parts getting too sluggish or blocking after CLP use.
