I was cleaning the old seam sealer out of the roof edge when I noticed very small hair line cracks along the curved (rolled) edge of the fiberglass roof. They are very small but they exist full length on both sides. I know that I could place a tape along the entire length and seal this permently. Is there any other product such as a paint or roof coating? I don't want a short term fix, I'm willing to do the work to make this last. Bill
