Do I need to cut openings for fog lights or sensors?

This bumper ships as a solid panel. If your vehicle has OEM fog light cutouts or parking sensor holes, reference the factory bumper opening locations and mark them on the new cover before drilling. Test-fit the cover first to confirm alignment with your vehicle's bumper beam.

Will this work with the lower valance from my stock bumper?

The Eros design features an integrated lower valance profile. OEM valance panels typically will not fit this cover due to the revised air intake geometry. Confirm your bumper beam and bracket setup matches factory specs before ordering.

What should I do to prepare the surface before painting?

Sand and prep the FRP surface with appropriate grit per your chosen primer and paint system. The Raw FRP finish provides a stable base for adhesion. Follow your paint manufacturer's recommendations for surface prep, primer type, and topcoat application.
