Step 1: Remove Components

Open tailgate fully and remove any rubber bumpers or accessories that will interfere with mounting.

Step 2: Cleaning/Surface Preparation

* * Proper surface preparation is the most important step for proper adhesion!

WARNING: Do Not Remove Adhesive Backing from Protector Yet!

Carefully hold Protector in location, Protector folds over the top edge of the sill about½" (but DO NOT fold over until instructed). Note all areas to be cleaned plus ½" around outside of Protector. Clean underneath the sill (by the bumper), also (so the masking tape will stick).

Clean area thoroughly 3 times. Use a generous amount of rubbing alcohol and clean paper towels each time (rub hard), allow to air dry between each cleaning. Clean down in all body seams and corners.

Clean area one more time, but this last time dry the alcohol off with a dry paper towel. If you see any dirt/wax film streaks while doing this, repeat cleaning process until spotless.

Step 3: Installation

Do not remove adhesive backing until instructed.

Carefully place Protector in proper location and check for proper fit (normally a 1/8" - 3/16" gap will be around all outside edges). If any areas need trimmed, trim with sharp scissors. The upper corners normally need trimmed because of variances in the caulk used at the factory.

Lay the Protector out on a flat surface with the paper side up. Mark a line (with a straightedge) the entire length of the Protector ½" down from the top edge.

Kneel down at the rear of the Jeep® and place the Protector in place, the top edge should be even with the top of the “bump” when viewed directly from the rear and the ends should be equal distances from the body seams. The line you drew should be directly on the corner edge. Tape the bottom edge (only) down securely, you will be using the masking tape as a “hinge” to locate the Protector.

When you are satisfied with the placement, remove all of the adhesive backing paper and gently lay the Protector in place. Do not fold the top edge over yet. Remove the masking tape and rub the Protector down hard. Start running your fingers back and forth over the edge and slowly “roll” the top edge into place.

If you have an air bubble you cannot work to an outside edge, cut a small slit in the center of the bubble and press out the air.

Step 4: Reinstall removed components

Carefully trim out any mounting holes for accessories, tire bumpers, etc. Reinstall removed components.

NOTE: The "Clear Frost" colored Protectors will take a week or so (faster in warm temperatures) before the clear color will even out, the adhesive is very thick and viscous and it takes time for the adhesive to fully "wet out". Please do not be alarmed if, directly after application, the Protector looks spotty, you are only seeing the adhesive through the clear material.


No maintenance is required, clean with a soft brush and soapy water.
Do not direct pressure washer sprays at an angle around the edges for 10-14 days after installation.

If the Protector ever needs to be removed, a hair dryer can be used to start a corner and it can be pulled off, but this will destroy the Protector. Alcohol will soften the old adhesive.
