[CAUT] Protek and Sluggish Dampers

[Timothy Coates]

Conrad,

The rail has bushings that are about 10 years old.  They aren't overly 
worn and really haven't had problems with sluggishness until this 
winter (which hasn't been that harsh).  There were a few that were 
suddenly a little sluggish.   I Proteked them.  After about 5 hours, a 
tuning, and two hours of playing (all included in the 5 hours), they 
started sticking.

I didn't feel reaming was necessary when they have been working fine 
for years.  Maybe I misjudged.
