Will this interfere with my trunk or bumper seals?

No — this is a front lip that mounts to the lower bumper fascia. The two-piece split geometry is engineered to clear the factory seams and seal lines. Verify fitment to your specific bumper configuration before final installation.

Should I seal the carbon edges where the two pieces meet?

Carbon fiber is naturally weather-resistant, but sealing exposed edges at the seam prevents moisture from wicking into the material over time. A thin bead of automotive silicone or polyurethane sealant between the two pieces is good practice before installation.

Can I clear coat this, or does it come with a protective finish?

The weave arrives as raw carbon — no factory topcoat. Applying a UV-protective clear coat is recommended to preserve the twill pattern and guard against sun fade. Sand the surface lightly before coating to ensure adhesion.
