Does this bumper have sensor cutouts or fog light holes pre-drilled?

No. Verify your vehicle's OEM bumper hole locations and sensor positions before drilling. Mark drilling points clearly to avoid damage to the inner structure.

What surface prep is needed before painting?

Sand and prep the surface thoroughly with the grit appropriate to your chosen primer and topcoat system. Follow your paint manufacturer's prep guidelines for adhesion and finish quality.

Does this single-piece design create any fitment gaps at the body panel edges?

Alignment depends on mounting point precision and bodywork condition. Test-fit the bumper before final fastening, and use shims or adjustment as needed to close edge gaps evenly.
