Will this fit my OEM mounting points?

Yes. This bumper is engineered for factory bolt-hole alignment. Before installation, verify your vehicle's mounting tab locations match the panel cutouts.

Are there sensor cutouts or fog light holes in this panel?

The bumper ships as a solid panel. If your vehicle has factory sensors or fog lights, measure and mark hole locations on the cover before drilling to ensure proper fitment.

What prep work does this need before painting?

Sand and prep the surface per your paint supplier's recommendations for adhesion. The FRP is delivered raw FRP, so clean any dust before application of your chosen topcoat system.
