Will this bumper cover my existing fog lights or sensor cutouts?

The B-2 profile is a full cover without factory cutouts. If your setup requires fog holes or sensors to remain active, you'll need to carefully mark and drill through the panel before primer application. Reference your vehicle's OEM bumper hole locations as a template.

How should I prepare this for paint?

Sand the surface with standard body prep techniques to remove the mold release agent and create tooth for primer adhesion. Once sanded and cleaned, apply your chosen primer and finish. FRP accepts most automotive paints and primers without compatibility issues.

Will this fit with my aftermarket rear diffuser or undertray?

Measure the lower edge of the B-2 profile against your diffuser or undertray before installation. The bumper sits at the OEM mounting points, so fitment depends on your other components' positioning. Test-fit first to confirm clearance.
