<HTML>Ladies and gents, I went out on a service call last week to deal with a rental piano that had sticky keys.  It was a Kawai console that was in a room approximately six feet from an open window.  It IS January, and even though this is California, there was a substantial amount of cool, damp air blowing in from outside.  After a brief and kindly lecture about the evils of drafts and temperature/humidity fluctuation, I set to work. There were many sticking keys and sluggish hammers.  It was tight centers, so I figured, hey, CLP will do the trick.  I was wrong.  For whatever reason, there was no noticeable improvement in the sluggishness. I assume that none of the excess fluid gets absorbed by the plastic as it might get absorbed by wood.  Anybody know for sure? I reamed a few flange bushings and replaced some corroded pins and the situation was resolved, but a less time-consuming solution would be desirable..  Anybody got an answer, and/or a lubricant that might work with Styran?   Dave Stahl</HTML>
