Will this interfere with the trunk seal or bumper cover when closed?

The V1 profile is designed to sit under the bumper line, not across the leading edge. Verify clearance at your mounting points before final installation — bumper fitment can vary based on previous repairs or panel alignment.

Should I drill through the panel or use adhesive to secure it?

This is your choice based on your desired permanence and reversibility. Adhesive works well for a clean, drill-free install. Mechanical fastening offers a more permanent bond. Prepare the mounting surface thoroughly either way — clean, degrease, and sand the bond area for best results.

Do I need to apply clear coat or paint this?

Carbon fiber benefits from UV-protective clear coat to maintain its finish and prevent oxidation over time. You can leave it raw if you prefer the weave texture, but protection is recommended for long-term appearance.
