[pianotech] What pin-driving fluid do you favor, David ???

[David Love]

It's a pure varnish resin without the driers, thinners or other additives
that I got from Rodda Paint (www.roddapaint.com) in Portland some time ago.
I don't recall the exact product and I don't have the original can anymore
but it thins with Xylene.  

I think the benefits of PDF are twofold:  First, once it dries it provides
the same benefit as Rosin applications to tuning pins.  Second, and perhaps
more important, it provides a lubricant for the pin when driving it into the
block that reduces stress on the wood fibers lining the tuning pin hole and
can cause a slightly reduced and less even torque.  A side benefit is that
it makes driving the pins easier.  It's a bit more time consuming but not so
if you are using rosin coatings anyway.
