If installing a patented ESI Tailgate Seal with Taper Seal® on the sides, install before ROK BLOCK® seal.

Important: Extreme temperatures will result in poor adhesive performance. Apply only if the air and surface temperature is
between 50° - 104°F (10° - 40°C). Avoid touching adhesive after removing liner, as this will weaken the bond strength.
