Hi All,  I just found another use for Phenoseal.  The rotating
pot metal portion of my Ampico A "modify" switch was badly cracked.
(Is it always the modify switch that goes bad first?  I have seen
three pianos with bad modify switches where the other three switches
were fine.)

I impregnated it with Phenoseal, let it dry and then smoothed the
sealing surface flat with a fine file.  The assembly now tests fine
with no leaks.  Does anyone know if the Phenoseal will penetrate well
enough to prevent further deterioration?
