Will this cover my existing rear bumper, or does it replace the whole assembly?

This is a cover that installs over your existing rear bumper using factory mounting locations. No cutting or modification of the OEM structure is required — it bolts on cleanly.

Does the Spec-R style include cutouts for sensors or backup lights?

Reference your vehicle's OEM bumper hole locations and sensor positions before installation. If your setup requires custom cutouts for parking sensors or other electronics, mark and cut after dry-fitting the panel to ensure proper alignment.

What prep work is needed before painting?

Sand the entire surface with appropriate abrasive to promote paint adhesion, then clean off all dust and debris. Apply your chosen primer and topcoat system per manufacturer specs. FRP accepts both single-stage and multi-stage finishes without additional sealing.
