It is now in Acetone in a glass jar for one day now. Tomorrow I&#039;ll move it to Laquer Thinner for several days. Then back to a paint thinner for a day or so, soaking in warm distilled water for a day, then on to my Kitchen window sill while still damp. </p><p>&nbsp;<img src="http://i232.photobucket.com/albums/ee219/carlagain/18.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>Difficult to notice the excessive shine on from this photo but it is highly polished. After a few weeks and then breathing on it, I&#039;ll try some more photos. Let you all know.</p><p>Presently have a Walker Half and a Mercury Dime on that window sill for several weeks now. They too were extreamely polished.[/QUOTE]</p><p><br /></p>
