Overview
Show original supplier description
Part #: ST038K1
Made from the same impact-resistant material as BumperTopper, SillProtector is a custom-fitting, durable plastic guard that protects interior door sills from scratches and everyday wear and tear. SillProtector attaches directly to your door sill surfaces using very high-bond adhesive strips. Installation is simple: clean the door sill, then clean the SillProtector itself with the provided alcohol pad. Peel back the adhesive liner on the product and press into place. As a bonus, when it's time to trade in your vehicle, SillProtector also helps cover small scuffs and blemishes to protect resale value.
