Does this cover the factory fog light openings?

The bumper cover is solid across the front — you'll need to cut out fog light holes if your setup requires them. Test-fit the cover first and mark any cutout locations before taking a saw to it.

Will this fit if I have a lower valance or air dam?

Lower valance compatibility depends on your bumper's total depth and how far the valance extends. Dry-fit both pieces together before committing to fasteners or adhesive to confirm clearance and alignment.

What prep is needed before painting?

Sand the surface with medium-grit sandpaper to scuff the primer, then wipe clean. Use your preferred primer and topcoat system — the cover is ready to accept paint once prepped.
