I will. I know there's some sort of strip that sometimes finds its way onto the lower "pinch-welds" of fuel tanks, but I think those are usually hard "chrome" plastic?
I do have some thin, tape-like adhesive-backed neoprene, which I suppose I could cut into a narrow strip and apply it, folded over, around the perimeter of the door. But it's much softer and not nearly as sturdy as rubber, no idea how well it would work or how long it would last, especially if it gets wet or exposed to sunlight long-term...
