Do the fog light cutouts line up with my truck's lights?

Yes—the cutouts are pre-positioned to match factory fog light locations. Check fit before final fastening; minor trimming may be needed depending on your light bezels.

Will this cover close gaps where my old bumper cracked?

This is a cover, not a full replacement. It mounts over your existing bumper structure, so if the underlying frame is damaged, address that first for proper sealing and alignment.

What prep work do I need before painting?

Light sanding with 220-grit or higher is standard for primer-ready parts. Use a filler primer if needed, then topcoat. Follow your paint manufacturer's instructions for adhesion and cure times.
