key bushing miracle stuff

[Mike Morvan]

Tom,
    There is NO miracle stuff or silver bullets in this business. Lightly 
steaming the bushings will give you the same temporary effect you achieved 
with VS Profelt without the damaging properties of embalming the mortises 
with irremovable silicone. If the bushings are worn they are worn, the cloth 
is eroded. Cloth is very hygroscopic and will swell readily with liquids but 
will assume their eroded shape quickly with some play. It is a very 
inexpensive quick fix though. Just my two cents. Mike
