I am stupid, and bought a solar cover about 3 feet too short . For a while, I just used the material I cut off the sides to cover the far end, but I'd like to attach it to the rest of the cover so I reel it all up without having to deal with two pieces.
I tried using 3M spray glue, since that stuff usually sticks anything to anything! It held for a couple weeks, but has started to come apart. Has anyone done successfully done this Ideally I would melt the two pieces together (like the manufacturers do), but I can't think of any way to do that myself.
