Frequently asked questions
- Does the bumper need to be drilled? No. It is securely fixed with the included high-tack 3M tape. We recommend cleaning the surface with alcohol before installation.
- Can it be painted another color? Yes. Although it comes in gloss black ready to use, the ABS surface accepts primer and paint for customization.
- Does it affect the car's warranty? No. As an externally-mounted cosmetic accessory, it does not interfere with the vehicle's mechanical warranty.
