Will this bumper work with my factory fog lights?

This cover ships without cutouts for fog lights. If your vehicle has factory fog light housings, you'll need to carefully cut the openings to match your existing fog light diameter before painting and installation.

Does the bumper cover mount to the original impact bar?

Yes. This cover is designed to bolt directly to factory mounting points on the existing bumper beam. No frame modification is required.

Should I paint this before or after installation?

Either method works. Painting before installation is faster and cleaner. If you paint after installing, mask off adjacent body panels carefully to avoid overspray on fresh paint.
