How to Install Cervini's 1965 Style Quarter Window Louvers - Unpainted (05-09 All) on your Ford Mustang

NOTICE: PRE-FIT BEFORE PAINTING! TEST FIT & INSTALL NEW PARTS ACCORDING TO THESE INSTRUCTIONS.

PAINTED OR ALTERED PARTS ARE NON-REFUNDABLE!

THE SURFACE TEMPERATURE WHERE THE 3M 2-SIDED TAPE IS APPLIED, MUST BE CLEANED WITH ISOPROPYL ALCOHOL & BE A MINIMUM OF 75 DEGREES F. ALLOW THE 2-SIDED TAPE TO SET 24 HOURS BEFORE DRIVING!

Pre-fi tting the Quarter Window Louvers: Align the template with the factory bodyline on the top of the quarter panel and the painted edge behind the window molding as shown in fig A. Tape the template in place. The same template is used for both sides.

Installing the Louvers: After the Louvers have been painted, install the provided 3M double sided tape along the guideline about an 1/8” away from the outer edge of the Louver as shown in fi g B. Mask off the red backing of the double sided tape and the Louver openings with 2” masking tape, leaving the center portion of the Louver exposed. Scuff the inside surface with a gray scuff pad and paint it with flat black paint. Remove the tape backing, place your fi nger tips under the rear of the louver, do not allow the double sided tape to touch the car. Align the front of the Louver with the front of the template, pressing firmly on the Louver adhering the double sided tape to the car. Work your way to the rear of the Louver applying pressure. Make sure to align the top of the Louver with the top of the template, removing your fingers last.

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.
