How to Install Cervini's Stalker Rear Wing - 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 trunk and quarter extensions: If you have a factory trunk wing, it will need to be removed. This wing is designed to cover the holes in the trunk. (If you do not like the tabs on the wing you can cut them off. But, you will have fi ll in the front two wing holes and paint the trunk.) Hold the trunk extension in place and check the alignment from the left to the right. Hold the quarter extensions in place and check the alignment with the quarter panel, rear bumper and trunk extension gap.

Step 1, Installing the trunk wing: After the trunk extension has been painted, install the 1/2” 3m double sided tape along the guidelines an 1/8” away from the outer edge of the part and use the 1/4” double sided tape along the brake light opening as shown in fi g A. Use the supplied template to cut out two tab pieces, on one of the 2x2 blocks of double sided tape as shown in fi g B. Peel and fold about 2” of the red backing from the ends of each piece of tape. Place the trunk extension on the trunk so that the backing is exposed and can be pulled. (This will allow you to get the best alignment of the part.) Pull the backing slowly. After all the backing is removed, fi rmly press the edges of the extension to securely adhere the tape. Open the trunk and install the small black screws through the factory wing holes into the pre drilled holes in the trunk extensions as shown in fi g C.

Step 2, installing the quarter extensions: After the quarter extensions have been painted, install the 3M double sided tape along the guidelines an 1/8” away from the outer edge of the part. Use the 2x2 block of double sided tape on the bottom of the quarter extension as shown in fi g D. Peel and fold about 2” of the red backing from each piece of tape, also fold the backing from each square of the tape. Then, place the trunk extension on the quarter panel so that the backing is exposed and can be pulled. (This will allow you to get the best alignment of the part.) Pull the backing slowly. After all the backing is removed, fi rmly press the edges of the extension to securely adhere the tape.

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.
