[pianotech] parts replacement due to vertigris

[Gerald Groot]

Sort of, is right.  On most serious vertigris actions, it is a waste of $$
to attempt to lub it.  1.  It comes back.  2.  Most often, it doesn't work
to free it all up as it should.

I suggest if the customer really wants to save $, you just continue to
protek, goose juice, whatever, every service.   I have many customers with
sluggish parts and lube works until the next service...sort of.   Don't
waste $ on a half way repair, which will eventually need replacing...what
will the customer think then...?
