In the last couple of years we have had a couple small leaks in our roof. So...up with the lap sealant I go. But ????? I have to wonder why folks don't use, (or at least talk about it) tape. Not the duct tape variety, but the stuff made by companies like Dicor and the like. I think it comes in 2 and 4 inch width. Says that removing it will cause permanent damage. Must be good right ? Anyway, why not use it for every seam on the top of the camper ?
