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

This is a blank panel — you'll need to reference your current bumper's fog hole locations and mark them on the new cover before cutting. Dry-fit first, then carefully cut from the back side to avoid chipping the front surface. Sand the cut edges smooth before priming.

Does this bumper work with factory parking sensors, or will I need to modify sensor mounts?

If your vehicle uses OEM bumper-mounted sensors, you'll need to assess hole placement on this new panel and drill or route access as required. Check your current bumper's sensor locations and plan your cutouts before assembly — this ensures a clean install without last-minute modifications.

What prep should I do before painting?

Sand the entire surface with appropriate grit to scuff the primer coating, then wipe clean with a tack cloth to remove dust. Fill any voids or imperfections with polyester filler if needed, sand again, and you're ready for color coat. Always follow your paint manufacturer's prep guidelines for adhesion.
