Will this work with my factory fog light cutouts?

This cover is designed for OEM integration, but fog hole positioning varies by specific trim. Reference your vehicle's original bumper hole locations before final installation to ensure alignment with your lighting setup.

Can I prep and paint this myself before bolting it on?

Yes — that's the advantage of receiving it in raw FRP condition. Sand and prep the surface using your chosen finishing method, then mount it once your paint or powder coat is cured. Install off-vehicle if possible to avoid masking headlights and trim.

Does the lower valance portion line up with factory sensors or brackets?

The cover is engineered for OEM mounting points. If your vehicle has factory bumper sensors, verify their location against the cover's panel layout before final fitment. You may need to drill sensor cutouts to match your specific bumper configuration.
