Will this cover my OEM fog light cutouts, or do I need to drill new holes?

This bumper ships as a solid panel. You'll need to mark and cut fog light openings to match your vehicle's OEM fog lamp positions. Reference your factory bumper or service manual for accurate hole placement before cutting.

Does this bumper work with factory parking sensors?

The panel ships solid. If your vehicle has OEM bumper sensors, you'll need to drill corresponding holes in the correct location to maintain sensor function. Consult your OEM bumper diagram to identify sensor hole locations before installation.

What's the best way to prep this for paint?

Sand the primer surface with medium grit to scuff the finish, then clean thoroughly to remove dust. This gives your base coat and topcoat proper adhesion. Follow your paint manufacturer's instructions for primer compatibility and application.
