| Chevrolet Silverado with Multi-Flex Tailgate |
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). If 45° - 55°F (7° - 13°C). Avoid touching adhesive after peeling off red liner.
Repositioning of seal should not be done more than 3 times and only once should the temperature be above 80°F (13°C).
Note: Enclosed 14” Large Tailgate Seal with Taper Seal® will only be used for STEP 6. Use enclosed adhesion promoter for STEP 7. |
STEP 1
Clean area thoroughly with soap and water solution and wipe completely dry. Use alcohol pads to prep the tape application areas and let dry. Figures and pictures shown are for left side main tailgate and inner tailgate. |
|
STEP 2: ATTACHING TO LEFT SIDEWALL OF MAIN TAILGATE
Start 1” (2.5 cm) below truck bed floor and attach seal to the rear corner edge of the left sidewall extension (FIG 2A). When nearing top of sidewall, gradually rotate seal 90° counter clockwise so that bulb is facing in-ward and the taped side of seal is flush with the sidewall at the top (FIG 2B). Cut to fit. Apply light pressure to adhesive. Duplicate for other sidewall. Do not close tailgate. |
 |
 |
|
STEP 3: ATTACHING TO INSIDE TOP OF TAILGATE
Cut and attach a 2” (5.08cm) piece to the tailgate at the top, bulb side facing down. Apply light pressure to adhesive (FIG 3A and 3B). Duplicate for right side. Do not close tailgate.
|
 |
STEP 4
Close tailgate. If you see light, make adjustments by removing the seal and repositioning. After seal is in place, apply very firm pressure (25lbs.) to secure the entire adhesive bond. |
STEP 5: ATTACHING TO PERIMETER OF TAILGATE GAP FOR INNER TAILGATE
Open inner tailgate. Start at either side and begin attaching seal, bulb side facing outwards and recessed .750” (1.9cm) from edge (FIG 5A and 6A). Apply light pressure to adhesive. Gradually round corner (slight ripples will exist at the corners and will not affect performance) and recess seal .250” (0.635cm) from edge for entire horizontal length of tailgate gap. Gradually round corner on the other side and recess seal .750” (1.9cm) from edge. Cut to fit. Do not close tailgate. |
 |
STEP 6: ATTACHING 2 ½” LENGTH PIECE OF LARGE TAILGATE SEAL
Cut a 2.5” (6.35cm) length piece from large tailgate seal and attach, bulb side up, to the side of inner tailgate (FIG 6A and 6B). Flush to top of tailgate. Apply light pressure. Duplicate for other side. Do not close tailgate. |
 |
 |
STEP 7: ATTACHING TO LEFT SIDEWALL OF INNER TAILGATE
Start near the bottom of sidewall and attach with bulb side facing to the right. When nearing top of sidewall, gradually rotate seal 90° counter clockwise so that bulb is facing inward (FIG 7A and 7B). If adhesive is being applied to a surface other than paint, then use enclosed adhesion promoter after determining position and prior to attaching seal. Apply light pressure to adhesive. Duplicate for other side. |
 |
STEP 8: CLOSE INNER TAILGATE AND INSPECT FOR LIGHT
If you see light, make adjustments by removing the seal and repositioning. Do not attempt to reposition any part of seal that was adhered using adhesion promoter. After seal is in place, apply very firm pressure (25lbs.) to secure the entire adhesive bond. Close inner tailgate. |
|
STEP 9: ATTACHING TO HORIZONTAL GAP OF MAIN TAILGATE
Position bulb side down and adhere to the tailgate gap just below the lower lip area of the extended truck bed floor (FIG 9A and 9B). Start at either end and flush to seal on the sidewall. Peel liner and attach in sections, apply light pressure to adhesive. Flush with seal on other side and cut to fit. After seal is in place, apply very firm pressure (25lbs.) to secure the entire adhesive bond. If air temperature will fall between 50°F (10°C) within the next 24 hours or, if seals are attached to a surface other than paint, then leave tailgate(s) open for 24 hours.
