I need your help in repairing a 1 inch slice in the bottom of my vinyl pool. The slice is a curve and depressed about 1/4-1/2 inch. It is about the size of a quarter. I have seen patches that I would apply cement and some that I would peel and stick. What are your recommendations and experiences? The slice was caused by dropping a piece of vinyl clad metal deck railing that dropped end first into the pool.
