Do I need to remove the OEM bumper to install this?

Yes. You'll need to unbolt the factory cover and transfer any existing mounting brackets or hardware to the new panel. The OEM attachment points align with this cover's design, so fastening is straightforward once removal is complete.

Will sensor cutouts need to be drilled?

Check your vehicle's OEM bumper for existing sensor hole locations and spacing. If your model uses rear parking sensors or cameras, reference those hole positions and mark them before any drilling or installation. Your vehicle's service manual will confirm sensor placement.

What preparation is needed before painting?

Sand the surface with appropriate grit to achieve adhesion, then wipe clean of dust. Apply your chosen primer, base coat, and clear coat per manufacturer specs. The FRP surface accepts standard automotive finishes without special prep equipment.
