We are going into our third Summer with our fiberglass (SWG) pool and are thinking about tiling the waterline this year before we open. I just spoke to the person who will be opening the pool and he thought that we would be crazy to tile a fiberglass pool in New Jersey considering how cold it gets here. He felt that the tile would not be able to withstand our weather. Has anyone out there had problems in the Northeast with their fiberglass pools and tile? I don't want to spend the $$$ if they're not going to stay on through the winter or start popping off soon after installation. Any thoughts or recommendations out there?
