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 </div> </body> </html>
