Does this cover have fog light cutouts?

No. The MS design features a clean, solid front panel. If your vehicle has fog lights, you'll need to carefully cut the openings to match your OEM hole locations and wiring setup.

Will this work with my bumper sensors?

Yes, if sensor holes align with your existing bumper. Before installation, verify your OEM sensor hole locations and mark them on the new cover so you can drill and mount the sensor bodies before final paint and install.

What's the best way to prep this for painting?

Sand the primer surface with medium-grit sandpaper to ensure good adhesion, then wipe down thoroughly to remove dust. Follow your chosen paint system's prep requirements — epoxy primer and urethane topcoat is the standard approach for FRP bumpers exposed to UV.
