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.
