Hey Don<br><br>Mb-12 should really have no affect on it,I know it says it works on many a "granite" but I have never had luck using the 12 on Granite now the mb-18 for granite working it wet to dry works great,and of course if powder alone wont work you would have to face polish with a "good" set of granite diamonds I like Maurizio's personally.I want to take Michael of Stone Henge top polishing class I would love to see his techniques and pick his brain and that of my peers,so much good information out there from all of you!!<br><br>Good Luck<br><br><b><i>Don Semi &lt;don@restoremarbleandgranite.com&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> <div dir="ltr"><div>Hi all:</div> <div>&nbsp;</div> <div>Customer has Labradorite Blue granite counter. It has one spot about 4' x 4" that has no polish to it at all. Another area is developing also. He indicated that he had a guy out a year ago
 who "polished it right out". To me it looks like resin breaking down. They indicate it has not been sealed. I tried some of MB-12 on it to no effect. Left an acetone poultice on the most obvious area. I am to call them tomorrow. I know it is late but any help or suggestion would be appreciated.</div>  <div>&nbsp;</div> <div>Thanks<br clear="all"><br>-- <br>Don Semi<br>Granite &amp; Marble Restoration<br>Dedicated to the Preservation of Fine Surfaces<br><a target="_top" href="mailto:don@restoremarbleandgranite.com">don@restoremarbleandgranite.com</a><br> 303-249-7909<br></div></div> <hr> <div>Powered by <a target="_top" href="http://www.discussthis.com">http://DiscussThis.com</a> <br><a target="_top" href="http://www.discussthis.com/members/sccpartners@stoneandtilepros.com"> Visit list archives, subscribe, unsubscribe or change your subscription preferences </a> <br> <a target="_top" href="mailto:sccpartners@stoneandtilepros.com">Start a new conversation (thread)</a> </div> </blockquote><br>
