Bests & Worsts Reviews from Amazon

Product works as expected. As a test, I treated the unpolished side of a granite tile with this product as directed, and placed a drop of RC cola on it. I compared that tile to an untreated one. As you can see in the photos, the treated tile not only caused the drop to bead up, but after 5 minutes, it was still beaded, while the cola had soaked in to the untreated tile. I then wiped the remaining cola off both tiles, and there was no trace of moisture in the treated tile, while there was clearly a dark spot in the untreated tile. I'm pleased.
