How to Install Cervini's Stalker Side Skirts - Unpainted (05-09 All) on your Ford Mustang

Notice: Prefi t Before Painting. Install new, unpainted parts according to these instructions. Then remove parts, paint them and re-install.

Painted or Altered Parts are Non-Refundable

The surface that is in contact with the 3M 2-sided tape must be cleaned with isopropyl alcohol & the temperature must be a minimum of 75 degrees F, before applying . Allow the 2-sided tape to dry 24 hours before driving.

Pre-fitting the side skirts: Remove the factory side skirts and the plastic clips that hold them in place. Tape the supplied template to the inside of the rear wheel well, in front of the rear tire and drill an 1/8” hole in the marked locations as shown in fi g. A. Hold the new side skirt in place and install the factory plastic retaners in the front wheel well as shown in fi g. B. Use the provided small black screws to secure the back end of the side skirt to the pre-drilled holes in the rear wheel well. ( Do not tighten the screws at this time.) With the inside mounting fl ange touching the rocker there should be a 1/4” gap from the bottom of the door to the side skirt. While holding the side skirt in place open the door and drill a 1/8” hole through the existing holes in the mounting fl ange as shown in fi g. C. After the holes have been drilled install the small black screws provided in the hardware packet. ( Do not tighten the screws at this time.)

Installing the side skirts: Included in the hardware packet is a roll of 3M 2-sided tape. After the side skirts have been painted, install the 3m 2-sided tape along the guidelines an 1/8” away from the outer edge of the part as shown in fi g D. Peel and fold about 2” of the red backing from each end of each piece of tape, then place the side skirt on the car so that the red backing is exposed and can be pulled. Next, follow the same procedure as you did when you where test fi tting the side skirts.Pull the backing slowly. After all the backing is removed, fi rmly press the edges of the side skirt to securely adhere the tape. Tighten all screws at this time.

VERY IMPORTANT: The following painting procedures MUST be followed EXACTLYfor PROPER ADHESION and to prevent fish eyes. 

1. To remove any mold release contaminants, clean the back of the part fi rst. Using 2 new clean rags, saturate the fi rst rag with plastic prep cleaner* and begin cleaning. Then use the second rag to remove the prep cleaner. Continuously fold both rags to their clean sides during the process. Use 3 sets of new rags throughout the process. This prevents mold release contaminants from transferring to the painted surface. 

2. Repeat step one on the front of the part. 

3. Rinse the part with water. Apply a generous amount of Ajax® or sand fi x* to a red scuff pad* (3M Scotch Brite Brand) and scrub the surface to be painted THOROUGHLY (especially where the 2-sided tape is installed, on the back side of the part, and all the hard to reach areas). Then rinse with water and dry. The scrubbed surface should be dull. If any shiny spots show, repeat the process on those areas. 

4. Using another set of clean new rags, again clean the surface to be painted with plastic prep cleaner. 

5. Spray the surface to be painted with adhesion promoter* including the areas where the 2-sided tape is installed (follow the instructions on the can for application and drying time). 

6. Apply 3 to 4 coats of urethane primer* with fl ex additive* (follow the instructions on the can for application and drying time). 

7. Wet sand primer with 600 grit sandpaper. Be careful not to sand through the primer. If you do, you MUST clean those areas with plastic prep cleaner, apply adhesion promoter and prime. Once the primer has dried, wet sand the areas that were touched up. Your surface is now ready for paint.
