Installation Guide (Tailgate Emblem)
-
Clean the Surface: Wipe the target area on the tailgate with detergent or alcohol to remove dust, oil, and impurities.
-
Check Surface Condition: Ensure the surface is completely clean and dry – residual moisture or dirt will affect adhesive bonding.
-
Peel & Stick: Remove the protective film from the emblem’s adhesive backing, align it with the desired position, and press firmly for 10–20 seconds.
Tip: For optimal adhesion, avoid washing the vehicle or exposing the emblem to water within 24 hours after installation.
