Can anyone tell me where I might find some sort of universal weather seal. I am looking for something like a bubble or tube type seal but with just a flat surface to mount it with adhesive or tape etc. I don't need something with the molded in push connectors. I have about a 3/4inch gap between my jeep tub (not a 715) and a flat diamond plate half door I installed. my son complains about the rain coming through it!
