Hi Gordon:
I have treated around 60 pianos with CA, both with and without bushings.
Your first application will soak into the bushings and the excess will run
seep down into the pinblock. Be generous. Go around a second time (which I
do most times anyway) and that will insure that CA will wick down into the
block where you want it. My philosophy is more is better. I don't want to
come back later and reapply because I was stingy with the product the first
time.
If it is a grand, play it safe and remove the action to prevent seepage
past the pins. In a spinet like yours, before you flip the piano up on all
four, be sure any excess has been soaked up with paper toweling as it can
run down the strings and into the dampers. Ask me how I know..... Good
Luck
