How to Install Cervini's Type II Ducktail Rear Spoiler - 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-fi tting the trunk and quarter extensions: If you have a factory trunk wing, it will need to be removed. This trunk extension will cover the holes that are closest to the back of the trunk. If part # 2230 pedestal wing is being installed along with these extensions then mount it according to its instructions in place before proceeding. Hold the trunk extension in place and check the alignment from the left to the right. Remove the trunk extension and hold in place the quarter extensions, check the alignment with the quarter panel and the rear bumper.

Step 1, installing the trunk extension: Included in the hardware packet is a roll of 3M 2-sided tape. After the trunk extension has been painted, install the 3m 2sided tape along the guidelines 1/8” away from the outer edge as shown in fi g. A. Peel and fold about 2” of the red backing from the ends of each piece of tape, then place the trunk extension on the trunk so that the red 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.

Step 2, installing the quarter extensions: Included in the hardware packet is a roll of 3M 2-sided tape. After the quarter extensions have been painted, install the 3m 2sided tape along the guidelines 1/8” away from the outer edge as shown in fi g. B. Peel and fold about 2” of the red backing from each piece of tape, then place the quarter extension on the quarter panel so that the red 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.



PAINTING INSTRUCTIONS

VERY IMPORTANT: The following painting procedures MUST be followed EXACTLY for 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.
