Hi I have a question about my pool. I bought a foreclosed home with some pool issues. I have an older pool with fiberglass walls and cement bottom. I was wondering which paint would be better to cut the fiberglass walls and bottom with or do I need to different kinds of paint? The gel coat on the walls are cracked and faded and the paint on concrete bottom is chipped here in there . Could you please get back to me and let me know what you think.
