[R-390] Anti-Stickum Lubricant

[Harry Joel]

Just a thought, after reading the post about the problem
with making sticky auto-tune mechanism behave.

There is a possible neat solution I cam across during
my current restoration of an 150-year old grand piano.
I came across a graphite solution that after application
leaves a micro-thin coat of graphite on the surface of
any material its applied to. Should not gum up delicate
and tight tolerances between sliding metal parts. 
Its called DAG Graphite Lubricant. Dries quickly and is sold by
International Piano Supply. 1-888-668-3788

Their part number is 8E02016
Not cheap at $12.20, but the 4oz jar should go a long way

Nice people to deal with
