We purchased this home with a pool in November 2015. Now I am getting the pool ready and it has a Purex/Pentair/Pac Fab CC420P filter system. I am experiencing "fiberglass itch" from the lid. If I rest my arm on it, then it gets all prickly, itch as if I've been working with fiberglass insulation. Is there any type of clear coat polyurethane or anything else to seal the exterior so as to avoid this itch?
