Does this bumper have factory fog light cutouts?

No — this panel ships as a full cover without pre-cut fog light openings. You'll need to measure and cut or route your own holes if your build includes fog lights.

Will I need to modify the lower valance area for sensor compatibility?

The stock lower valance should remain compatible with this bumper cover. If your vehicle has factory PDC or parking sensors, verify sensor placement before final assembly to confirm no interference.

What finish options work best with raw FRP?

This bumper accepts standard automotive urethane or acrylic top coats. Sand the primer surface lightly before paint, and use a sealer to ensure even color match and UV protection.
