Will this cover existing bumper sensor holes?

This cover is designed for standard OEM bumper geometry. If your vehicle has factory sensor cutouts, verify their location and size against the panel profile before final fitment. You may need to carefully cut or drill to match your specific setup.

Can I use this with my lower valance or splitter?

The B-2 style maintains stock bumper proportions, so it works well with factory-height lower panels. If you run a custom valance or aggressive splitter, test fitment first to ensure clearance at the panel edges.

What prep is needed before paint?

Sand the primer surface with appropriate sandpaper, clean off dust, and fill any minor imperfections before applying your chosen basecoat and clear. FRP responds well to standard automotive paint systems when properly prepped.
