Will this interfere with my trunk seal or undercarriage?

The front lip mounts to the lower bumper area and does not extend rearward into trunk or door seals. Verify clearance with your specific bumper cover configuration before final installation.

Should I drill through or use adhesive to mount this?

Installation method depends on your bumper's existing mounting points and your preference for permanent versus reversible fitment. Inspect your bumper holes and evaluate adhesive strength for your climate before committing to either approach.

Does the clear coat need maintenance or reapplication?

The factory clear coat protects the carbon weave from UV and moisture. Regular washing and occasional automotive sealant application will extend its finish life. Avoid abrasive polishing compounds that can dull the surface.
