How to Install

For Best Results
Tools Needed: Heat gun or blow dryer, padded glove or felt-tip squeegee 

Step-by-Step Installation:

1. Rinse the entire rear diffuser fang application area with water/soap, or a 70% isopropyl alcohol spray.

2. Dry the surface completely to ensure there is no dust or residue on the surface or in the crevices.
   

3. Peel off the vinyl overlay from the backing paper one by one; they are cut to shape to fit your diffuser. All pieces are the same size to fit the middle fangs of your rear diffuser. You will be able to use either piece of vinyl for either portion of the middle fangs.
   
   
4. Make sure the pin-stripe is centered on the diffuser accent. Align the top portion of the overlay with the top of the diffuser fang accent, then tack it down to the surface.
   
   
5. Once aligned, the rest should fall into place. If it does not, peel it up carefully and reapply, ensuring you slowly guide the overlay into your desired placement after laying the top portion first.
   
   
6. Make sure you have a padded card or soft glove to put on your fingers; if you do not, your fingers will do fine to smooth out the overlay onto the diffuser.
   
   
7. Swipe left and right gradually to reduce bubbles
   
8. Once everything is laid out to your desired outcome, follow the steps below to ensure longevity and adhesion.
   
   
9. Post-heat the vinyl: Use a heat gun or blow dryer to remove small bubbles and activate the adhesive for stronger bonding.
   
   
10. If bubbles remain, press firmly with your finger or squeegee and swipe them out toward the closest edge.
    
    
11. If you make a mistake, gently peel off the overlay right away and reapply. Add light heat to remove wrinkles.

📌 Reminder: Always post-heat the vinyl after installation. This activates the glue and ensures maximum adhesion.
