How to Install Cervini's B2 Chin Spoiler - Textured Black (05-09 V6) 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

Pre-fi tting the chin spoiler: This chin spoiler is designed to fi t over the factory bumper. Remove the factory air defl ector from the bottom of the bumper. Remove the three screws in the left and right front wheel wells that attach the inner plastic wheel wells to the front bumper. Cut out the provided template (Use the same template for both sides.) and tape it to the bumper as shown in fi g A. Drill a 1/4” hole through the bumper as indicated on the template.​

Installing the chin spoiler: After the bumper has been painted install the provided 3M double sided tape a 1/8” from the top edge of both sides of the chin spoiler as shown in fi g B. Peel and fold about 2” of the red backing from the ends of each piece of tape. Hold the chin spoiler in place on the front bumper, so that the red backing is exposed and can be pulled. (This will allow you to get the best possible alignment of the part.) Reinstall four of the factory plastic retainers under the car through the ¼” holes in the chin spoiler. Pull the inner wheel well toward the tire and install the small black screws from the back side of the bumper through the ¼” holes you drilled in the left and right sides of the bumper. There are fi ve pre-drilled holes in the front of the four factory plastic retainers previously installed under the car and one on each side of the plastic retainers. Use a powered screw driver to screw in the provided silver screws to the bumper as shown in fi g C. Pull the tape backing slowly and fi rmly press the chin spoiler to securely adhere the double sided tape.

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.
