The soft plastics in your vehicle are susceptible to damage each and every time you get in and out of your vehicle. Accidental scuffs can appear almost out of nowhere.
These suede overlays give it a soft feel and don't show accidental contact as easily.
Installation
Make sure it is warm before you install these so the adhesive can bond properly. Clean the area and make sure it has no Armor All on it.
Test fit the product and then remove the backing and complete the installation.
