Our fiberglass pool coping is cracked and old. 40 plus years. Fiberglass repairs don't hold up. It appears that the coping on the pool deck and the sides of the pool are all one piece in 6ft wide sections. These sections go down the sides of the pool about 36 inches where they meet the concrete sides and bottom. Does anyone know how we can replace a section or if it is possible to just get a section, and cut out the top faux tile section that is cracked and make the install?
