How to Install Cervini's B2 Chin Spoiler - Unpainted (05-09 GT) 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 directly fi t over the existing factory GT bumper cover. Remove the 3 screws in the left and the right front wheel wells that attach the plastic inner wheel well to the front bumper. Remove the 4 screws under the car that attach the front bumper to the plastic shield. Cut out the provided template (use the same template for the left and the right sides) and tape it to the bumper as shown in fi g. A. Drill a ¼” hole through the bumper as indicated on the template. Once the holes have been drilled, hold the chin spoiler in place on the front bumper and reinstall the 4 factory screws under the car through the ¼” holes in the chin spoiler. Then pull the mud shield toward the tire and install the each screw from the backside through the ¼” holes you drilled in the left and right sides of the bumper. There are 4 predrilled holes in front of the 4 factory screws previously installed under the car, with a 1/8” drill bit, drill through these holes and into the bumper, then install the screws provided in the hardware packet as shown in fi g. B.

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.
