Trondak U-40 Cork Seal, designed to seal the surface of cork rod handles. It prevents the penetration of soils and other foreign matter transferred to the grip area from the fisherman's hands. It enhances that ``cork feel.`` It toughens the cork to aid in the prevention of sloughing, and chipping of the cork surface. Cork Seal soaks into the cork and seals in depth. Once it is dry, dirt, grime, salmon egg residue, etc., are easily washed off with soap and water.
