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.<o:p></o:p></DIV> <DIV> <o:p> </o:p></DIV> <DIV> Ron O.<o:p></o:p></DIV> <DIV> <o:p> </o:p></DIV> <BLOCKQUOTE style="MARGIN-TOP: 5pt; MARGIN-BOTTOM: 5pt" cite="" type="cite"> And then of course, have your buffing wheel available!<o:p></o:p></BLOCKQUOTE> <BLOCKQUOTE style="MARGIN-TOP: 5pt; MARGIN-BOTTOM: 5pt" cite="" type="cite">  <o:p></o:p></BLOCKQUOTE> <BLOCKQUOTE style="MARGIN-TOP: 5pt; MARGIN-BOTTOM: 5pt" cite="" type="cite"> Terry Farrell<o:p></o:p>  <o:p></o:p> <BLOCKQUOTE style="MARGIN-TOP: 5pt; MARGIN-BOTTOM: 5pt"> I have scraped it off with a razor or knife and then dressed the finish with a little 4/0 steel wool.
