Upright Hammer Butts

The bobbling I experienced in my own piano was caused by insufficient key
dip. The hammers were bouncing off the jack because it hadn't gotten out of
the way. I regulated the action and left plenty of after touch.... end of
bobbling.

  Hello, List!   I have been wondering if anyone has experience with
applying Teflon spray to upright hammer butts. or McLube?  I have a customer
that plays so lightly that the hammers are bubbling, and I tried a few
sample keys- giving more dip, changing the backchecks, moving the letoff,
etc.  None of the changes made her happy, and she claims that she doesn't
like the Click feel.  I usually apply powdered teflon to Grands, but I was
thinking that some spray would be certainly faster and easier.  I also know
that faster and easier is not always applicable.  Just wondering if anyone
does this, and their experience.
