In this particular case it is a satin finish. I don't think he'll need
the buffing wheel or polish.

Hi all,
 
CA can be dissolved with acetone. Acetone won't hurt polyester,
particularly if its only in contact with the polyester for a short time.
After you wash the CA off, just polish the polyester surface again with
any of the polymer polishes. It will take the slight dulling off to come
up just like new. But please make sure that the finish you are proposing
to removing the CA from is indeed polyester. If its acid cat or any of
the other lacquers, acetone will remove both the CA and the lacquer
coating.

And then of course, have your buffing wheel available!

I have scraped it off with a razor or knife and then dressed the finish
with a little 4/0 steel wool. You could even use some 600 sandpaper
first and then the steel wool. Try an inconspicuous area first to see
how it is going to look on the finish. But if you can hardly see it now
probably hitting a couple of times with the steel wool will make it
disappear.

I just finished tuning a satin walnut polyester piano that has a few
loose pins.  It's a couple of years old, and still under warranty, but I
figured I try to CA a couple of pins anyway. 
 
Just to prove that performing that operation requires care and patience,
I spilled a very small amount on the keyslip....:-([(
At least it isn't laquer.  I got most of it off before it had time to
set, but as we all know, the stuff dries durned fast!  So there are a
couple of very small marks on the front. 
 
The finish doesn't appear to be damaged at all, and it's hardly visible,
but I can see it.  I'd like to do right by the customer and get it off
if possible, but I didn't want to apply chemicals that might take the
finish off in conjunction with the glue...
 
If any of you have an idea about how to remove this stuff, please let me
know!
 
It's always on the fourth tuning of the day...
 
Thanks in advance!
