In my experience Protek CLP make some bushings very sluggish or even
blocking after some time.

Have no correlation between the kind of bushings (Renner most probably )
that produce these results on a regular basis.

The lists being mostly driven by US techs and Protek being an Us product
widely used, nobody seem to answer to these questions most probably because
of the political correct attitude on the lists (is not it guys ?)

So let me say that is how I understand your silence on that matter (strange
as you're generally willing to talk on any product/process used)



Happy Christmas to all.

The Steinway "Permafree II" action centers are impregnated with a teflon
solution, which lubricates and provides additional firmness. We had quite a
bit of discussion of this over the past couple months, with respect to
firmness versus friction.
    No other manufacturer uses this method. Most others are pure,
"unadulterated" felt, some have graphite applied to one surface. All others
will respond to lubrication with Protek, and/or to shrinking/sizing with
alcohol/water. Steinway will not respond to either, due to that
impregnation with teflon. Pure methanol, a controlled substance, is
available (at least in colder climes) as gas line "de-freezer." Eric
Schandall says he thinks ethanol will work as well.

When I was at Steinway last summer, I could have sworn Eric told us to use
Protek on the bushings. I will see if I can find methanol here in "warm and
sunny" Alabama.
