Collinite No. 435 Black Streak Remover + Protector handles black streaks, tough stains, and freshwater spots on fiberglass in a single step. As it cleans, it deposits a fast-bonding polymer layer that leaves behind surface protection — no separate wipe-down required. Safe for use on fiberglass, metal, and painted surfaces. Always test in a small, inconspicuous area before full application.
