I have a VERY substantial fiberglass extension ladder. It's so substantial, it nearly whips me whenever I need to use it. <br /><br />Anyway, whenever I need to clean out the gutters, I extend it and lean it on the gutter. As I climb, the fiberglass ladder and the metal gutter form no friction and the ladder dances around on the edge of the gutter. I'm not young and don't need no dancin' ladders.<br /><br />I'd like to glue some rubber strips on the edge of the portion of the ladder that rests on the gutter to stop the dancing and sliding around. <br /><br />My questions are, what would be an appropiate material and what should I glue it with?
