Trondak U-40 Perma Gloss, the ultimate one part urethane rod finish. For those requiring a water clear, non-yellowing finish that will outlast the rod itself in durability. The perfect finish for fly rods, light and medium spin rods, pack rods, and all cases where a large bulky buildup on the rod windings is objectionable. The perfect finish for any rod subject to constant sun and weather. An excellent coating for wood reel seats.
