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

The Velocity design includes the same fog hole openings as the factory bumper. Align the cover with your existing mounting points, and the cutouts will line up with your current fog lights — no additional drilling required.

Does this bumper fit over the lower valance, or does it replace it entirely?

This is a full front bumper cover replacement. It mounts in place of the OEM unit. If your vehicle has a separate lower valance or air dam, verify the fitment clearance against your car's specific bumper structure before install.

What should I do to prep the surface before painting?

Sand the surface with appropriate grit to create a smooth base, then wipe down to remove dust. Follow your paint supplier's recommendations for primer and topcoat application on FRP. Proper surface prep ensures the finish adheres cleanly and lasts.
