We have a fiberglass pool with a (what I believe) is a fiber light strip installed around the top inside edge of the pool. It has been screwed in and over the years, the water and salt has caused the screws to rust and erode, so the strip is pulling away from the pool wall. Has anyone else had this issue? This pool is new to us, and we are wary of adding more screw holes to the fiberglass. The strip works fine, it just doesn't look so good.
