I have an above ground aluminum pool that has developed a rust hole about 2 inches in diameter. The hole is about 24 inches above the bottom of the pool, but the liner hasn't torn through yet. Does anyone know how I can fix the hole? Can I just remove part of the liner, cut out the rust hole, paint around it, then rivet a new piece of aluminum over the hole? Do I have to replace the hole section of aluminum? Any ideas?
