Clean area thoroughly with soap and water solution and wipe completely dry. Use alcohol pad to prep the tape application area and let dry. Wait until after Tailgate Seal is installed before applying very firm pressure, to secure adhesive bond. If necessary, Tailgate Seal can be removed and repositioned prior to applying very firm pressure. Pictures shown below are for the left sidewall and tailgate gap.

To evaluate the best positioning for the tailgate gap, cut a 1” (2.5cm) test piece and align the top of bulb with the truck bed floor. Stand to the side of truck and raise tailgate until the bulb makes contact with tailgate. If the bulb rolls downwards just before closing tailgate, so that you can see the tape, then seal has rolled and compressed too much. This can cause added stress to the adhesive and possible separation.

If compressing too much, then invert 1” piece so that bulb side is down. Raise tailgate again and make sure no light is visible through the 1” piece. Adjust 1” piece higher or lower in the gap, as needed, to block the light.

After determining if bulb should be up or down and how high or low, remove 1” piece and pick up one end of the continuous seal. Start at either end, peel back liner and flush to tailgate seal on the sidewall. Attach in sections, apply light pressure to adhesive should you need to reposition. Flush to seal on the other sidewall and cut to fit. Apply very, very firm pressure to secure adhesive bond.
