Allen,

If there are no tuning pin bushings, lay the piano on its back with a piano
tilter, and apply the solution according to the directions on the brand of
solution that you chose.

If there are tuning pin bushings, the pin tightening solution has a pretty
hard time getting to the area that you are trying to treat.  In one
instance there was this older studio piano that I treated by drilling a
hole through the tuning pin bushings, and then applying the solution after
tilting the piano.  It was a little slower and more awkward.  It did work
for the most part, though I still had to replace some tuning pins that just
didn't respond.
