key leads

[Leslie Bartlett]

I have a piano to deal with next week- most of the leads are swelling.  They
can't afford to replace them, so my thought is to file them, then spray
lacquer on the lead.  The corrosion goes down very little into the actual
lead.
 
Also need to replace most if not all hammer return springs.  Does that lead
dust cause the springs to deteriorate and break?
