4. Installation Instructions (Setup)

While installation is designed to be straightforward using double-sided tape, professional installation is highly recommended to ensure proper fitment and long-term adhesion. No drilling is required for this installation.

Required Materials (Not Included):

• High-quality automotive-grade double-sided adhesive tape (e.g., 3M VHB tape)
• Surface cleaner (e.g., isopropyl alcohol)
• Clean microfiber cloths

Installation Steps:

1. Preparation: Thoroughly clean the surface of the vehicle's trunk lid where the spoiler will be mounted. Use an automotive-grade surface cleaner (such as isopropyl alcohol) to remove all wax, grease, dirt, and debris. Allow the surface to dry completely.
2. Test Fit: Carefully place the spoiler on the trunk lid without removing the adhesive backing. This step is crucial to ensure proper alignment and to mark the exact position for installation. Use painter's tape to mark the edges of the spoiler on the trunk lid.
3. Apply Adhesive Tape: Apply high-quality automotive-grade double-sided adhesive tape to the underside of the spoiler. Ensure the tape covers the entire contact area for maximum adhesion.
4. Final Placement: Carefully remove the backing from the adhesive tape. Align the spoiler with the marked positions on the trunk lid.
5. Secure Attachment: Press the spoiler firmly onto the trunk lid, applying even pressure across the entire length of the spoiler for several minutes to ensure proper adhesion. It is recommended to apply pressure for an extended period or use masking tape to hold the spoiler in place for at least 24 hours to allow the adhesive to cure.

Note on Venting Holes: The holes on the back of the spoiler are designed as venting holes and are not intended for the use of screws or any other mounting hardware. Attempting to use screws may damage the product and the vehicle.

5. Care and Maintenance

To maintain the appearance and integrity of your carbon fiber spoiler, follow these care guidelines:

• Cleaning: Regularly clean the spoiler with mild automotive soap and water. Use a soft microfiber cloth to avoid scratching the surface. Rinse thoroughly and dry immediately to prevent water spots.
• Protection: The spoiler features a UV-resistant clear coating. To further protect against environmental elements and maintain its shine, consider applying a high-quality car wax or ceramic coating suitable for clear-coated surfaces.
• Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or strong chemical detergents, as these can damage the clear coat and carbon fiber finish.

6. Troubleshooting

If you encounter issues with the spoiler, consider the following:

Adhesion Issues:

• Poor Adhesion: If the spoiler does not adhere properly, it is likely due to insufficient surface preparation or improper application of the adhesive tape. Ensure the mounting surface is meticulously clean, dry, and free of any contaminants before applying tape. Apply firm, even pressure during installation and allow adequate curing time for the adhesive.
• Tape Not Holding: Verify that you are using a high-quality, automotive-grade double-sided adhesive tape specifically designed for exterior applications. Standard tapes may not withstand environmental conditions.

For persistent issues, it is recommended to consult with a professional automotive body shop or installer.
