YC probably used very thin finish on it and it's torn through the finish.  Epoxy repair kit from pianotek or something similar should work....or a Sharpie! lol Paul <table width=100%> <tr valign=top> <td>From: <td>paul bruesch <paul@bruesch.net> <tr valign=top> <td>To: <td>Pianotech List <pianotech@ptg.org>, ptg_pianotechne@egroups.ptg.org <tr valign=top> <td>Date: <td>09/07/2011 01:25 PM <tr valign=top> <td>Subject: <td>[pianotech] Abrasions in polyester finish</table> <hr noshade> A new client I tuned for yesterday has a small YC grand. I noticed light/white-colored abrasions on the treble side of the black-polish case, right on the outside curve. When I asked her about how they came to be, she told me that they'd had it moved many times, so when they wanted it moved one MORE time, they decided to do it themselves ("It looks so easy when the pros do it"), and dragged it on a "soft carpet, only soft carpet". She's the first client I've ever known that had her own bottle of Cory High Gloss Finish polish (which I always bring, too) though the piano was quite dusty and well-smudged. As I cleaned, dusted, vacuumed, and polished with the Cory, I noticed that the abrasions seemed to be slightly reduced in intensity. It just occurred to me now that perhaps this could be buffed out? I didn't consider that possibility and took no photos while I was there. I just called the owner to ask if she could take a photo or two, but she cannot. Was the apparent reduction in abrasion likely my imagination? Or would it be worthwhile to try something with a very mild abrasive? I'm thinking something like "3M Imperial Hand Glaze 05990" And yeah, I know a photo would probably help a lot... sorry! Paul Bruesch Stillwater, MN
