      Totally agree, the crown on N.Y. must be treated but the shoulder and 
under strike point applications are preludes to the final Solution applied to 
the crown
   I would suggest clear Plexiglas dissolved in acetone. It takes a few days 
for it to melt initially into suspension. Far more flexible and seems to have 
the flexibility of its own as you seek. Used in enough to know that even when 
poured on heavy it doesn't get brittle like a too thick dose of a lacquer or 
keytop solution. Needles still penetrate it's very forgiving. You may even 
have trouble getting enough bite in certain hammers which means it's not that 
stiff a material unless abused. Sounds like this could work for you.
