Will I need to drill or modify my existing rear bumper reinforcement?

No structural modification is required. The cover mounts to your existing reinforcement using factory attachment points. Verify your mounting hardware is clean and secure before installation.

Does this cover have sensor or fog light holes?

This is a solid bumper panel. If your vehicle has OEM sensors or fog lights in the bumper area, you'll need to match those cutout locations to your specific setup before final installation.

What prep work should I do before painting?

Sand the primer surface lightly to accept your chosen paint or clear coat. Clean thoroughly to remove all dust and debris before application. Your paint supplier can recommend the best primer and topcoat system for FRP.
