Will this interfere with my bumper cover or air dam at highway speeds?

The Advancer lip is designed to sit flush with the lower fascia line and adds minimal extension. At highway speeds, smooth airflow passes naturally over the panel. If you run a lower air dam, verify clearance with your bumper's actual depth before final fitment.

Should I use adhesive or drill through to mount this?

This panel is engineered to use your factory bumper mounting points as anchor references. Adhesive-only installation works well for light-duty road use; drilling into the bumper and using fasteners provides more security if you drive aggressively or tow. Choose the method that matches your driving style and comfort level with the existing bumper structure.

What prep work do I need before painting?

Sand the surface with standard automotive sandpaper and wipe clean before applying your chosen basecoat and clear. Follow your paint manufacturer's guidance for surface prep on FRP panels. A clean, scuffed surface ensures the best adhesion and finish.
