Marc with Pool Tile Dr is as good as it gets. He is professional, courteous, and punctual. His knowledge of the process is exemplary and he is detailed in both cleaning the tile and cleaning up after the tile has been polished.
It makes a huge difference over using a pumice stone and slaving away with elbow grease and about 10 beers...
My pool is shown in pictures 6 and 7. Very clearly the process works and I highly recommend this company.
