Closed the pool yesterday and was thinking about opening next season already! While I was Home Depot shopping for some other things, I came across those 6' lengths of polyethelyne pipe insulation and figured I could use them around the perimeter of the pool cover to keep leaves from accumulating under the cover around the coping. I went ahead and bought 20 of them and got some of those 1" barbed couplings and installed it all. The edge of the cover holds down the "noodles" quite well and the hose barbs keep it all joined together. The coping has a raised bullnose edge and everything is nice and tight. Hopefully this will prevent leaves and bugs from staining my white coping and make opening a bit cleaner and easier. I wonder if anyone else does something like this?
