How to install Extruded Solutions' Tailgate Seal with Taper Seal®

ITEMS REQUIRED: Scissors, clean rag and soap solution.

Extreme temperatures will result in poor adhesive performance. Apply only if air and surface temperature is between 55° - 105°F (13° - 40°C).
Avoid touching adhesive after peeling off red liner. Repositioning of seal should not be done more than 3 times and only 1 time if the temperature is above 80°F (13°C).

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 (25lbs). Pictures shown below are for the left sidewall and tailgate gap.

Start 1” (2.5cm) below truck bed floor and attach seal to the rear corner edge of the left sidewall extension (FIG 1B). Stop when flush with rubber stop. Cut to fit. Apply light pressure to adhesive. Continue up from rubber stop to next rubber stop. Cut to fit. Apply light pressure. Duplicate for right sidewall.
Cut and attach a 2" (5.1cm) piece, Large Tailgate Seal, to the top of sidewall. Attach so that bulb is facing inward (FIG 2B). Apply light pressure to adhesive. Duplicate for right sidewall.

Cut a 1.375" (3.5cm) piece and attach, bulb side facing outward, and attach as shown in FIG 3.


Start at either end of the tailgate gap and flush with Tailgate Seal on the sidewall. Remove liner in sections and attach bulb side down and adhere just below lip of tailgate gap (FIG 4).

Cut and attach a 1.750" (4.5cm) piece to the inside of tailgate near the bottom (FIG 5A and 5B). Apply light pressure. Duplicate for the right side
Close tailgate. If you see light through the sidewalls, make adjustments by removing the seal and repositioning. If there is still light, then cut pieces of seal as needed and attach to sidewalls and/or tailgate. Do not attach adhesive to seal. After Tailgate Seal is in place, apply very firm pressure (25lbs) to secure the adhesive bond.
