Will this cover my fog light cutouts and sensor holes from the OEM bumper?

No — this bumper cover replaces the OEM face panel entirely. Your existing fog light openings and sensor locations will need to be transferred or re-cut to match your vehicle's lighting and safety system placement. Measure and mark your OEM cutout positions before sanding and prepping the new cover.

Do I need to remove the lower valance or radiator support to install this?

This is a direct replacement for the bumper cover face panel only. The underlying support structure stays in place. Disconnect your OEM lights and sensors, unbolt the old cover, and bolt on the new one. Your existing lower valance and crash bar remain untouched.

What prep work is needed before painting?

Sand the entire surface to uniform profile and remove mold release compound with soap and water. Fill any surface imperfections with spot filler, sand smooth, and apply your chosen primer and paint system. FRP accepts standard automotive primers and topcoats when properly prepped.
