Does this bumper fit the OEM lower valance and sensor openings without modification?

Verify alignment with your vehicle's existing lower valance and front parking sensors during test-fit before finalizing installation. Some sensor hole positioning may require adjustment to match your specific model year.

Should I paint this before or after installation?

Either approach works — painting before install protects the new finish from handling scratches and ensures even coverage. If painting after, sand and prep the surface thoroughly before applying your chosen finish.

What's the best way to finish polyurethane for durability?

Sand the bumper with fine-grit paper and apply a quality automotive paint system. Clear coat is recommended to protect against UV damage and maintain gloss over time. Follow your paint manufacturer's specifications for primer and topcoat compatibility.
