Stan,

I would like some advice on buffing out polyester pianos.  What 
kind of buffer is the best.  Polishes?  What to look out 
for when attempting this work.  I have many pianos that could 
really benefit from this work and I would like to be able to 
offer the service.  Many years ago I help prep pianos for a 
dealer at a "warehouse".  They had a great touchup man who used 
this hand-held electric buffer.  I believe he squirted on some 
kind of a polish as he buffed the finish.

Thanks in advance...
