Hi all:
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.
