FAQ

• Does this require drilling the bumper? No. It secures firmly with the included high-tack 3M tape. Clean the surface with alcohol before installation.
• Can it be painted a different color? Yes. While it comes gloss black ready to use, the ABS surface accepts primer and paint for customization.
