Customizing a piano

[Ed Sutton]

Well...somebody has to say it:

Ballistol (Gun oil) is commonly recommended by major German manufacturers as 
an action lubricant.
As recently as June 2008 it was recommended by a well-known American piano 
designer in a class in Anaheim.
It is especially recommended to lubricate leather key bushings.
Diluted with alcohol it is used like Protek.

As to any distinct differences between German Ballistol and Hoppes gun oil 
(which Alicia used), I cannot speak.

Best regards,
