Don, You concentrate the polishing on the bottom of the pin? It seems you would only be able polish the sides of the pins...to be sure I understand: action tipped on the keybed, keys up and going at it similar to Yamaha's method of split punching insertion? If Kawai concert technicians do this, I'm going to make a polishing mute, maybe another lubricant other than silicone...although I have a bottle I've yet to open... I imagine the split opens when pressed against the keypin and puts some pressure on the keypin? Seems like a good idea. Kawai doesn't see the necessity of a metal polish? I understand Japanese concert techs travel light...
