Perma Glaze of Western Wisconsin Reviews (1)
We had a bathtub permaglazed and immediately noticed a rough area 1 inch by14 inches down the middle of the bottom which shortly thereafter began chipping. The owner came out, said something had been dropped on the area (by us), touched it up and charged for the service. A month or so later more areas had lifted, the owner came back with a bad attitude, again accused us of dropping things onto the floor of the tub, touched it up again and very reluctantly did not charge me after I objected to the charges. He left saying he didn't want to deal with problem anymore and recommended I pick up some touch up paint for future problems.
This problem, in my mind, is the result of faulty surface preparation. My wife and I are the only ones in the house and haven't dropped anything in the tub. This may be a good product but I would not use Permaglaze of Western WIsconsin for your project.
