I know this topic has been talked about before. I was wondering if anyone out there was a distributor of this or knows anyone who is? After researching Crystal Guard, there have been some very interesting posts regarding this product. It seems to be a very durable sealant. The post on here so far have dealt with the quick detail version. Has anyone used the EX? I was thinking this might fit in my repetoire after I remove the swirls. I was also thinking this may be a good sealant to get through Ohio`s harsh winters.
