The DEP installed a new dock on our local lake, which has white rubber bumper rails on it. I had my nonboater hold my boat in place by the dock while I got my truck and loaded the boat. I guess he let the boat rub on the dock, because when I got home, I noticed I had a few 4 to 5 inch white marks on my rub rail. What’s the best way to get these white rubber marks off? I thought perhaps a magic eraser, but wanted to ask you guys for help first. Any feedback would be most appreciated. Steve
