We were renovating our bathroom and look to this as a away to save some money by reglazing the existing bathtub. It took a day tostrip the tub the reglaze it. IT llok great when ti was deon as the previous owners had tried to glaze it themself and it looked terrible.
6 months to a year later we noticed a bit of the glaze coming off in a small area so phoned the company. The dispatcher did mention that this could have been done by something dropping onto the tub and causing the enamel to chip off. She said they would call us back but never did.
We did find that with two young kids it was easy to get a few chips in the enamel. Overall is was a good experience in terms of money saved and how much beter it looks. We're just not sure about the durability.
