Does this grille need clear coat protection?

Yes. Carbon fiber benefits from a quality clear coat to protect against UV exposure and maintain the weave finish long-term. Apply clear coat after installation and allow full cure before washing. This preserves the visual depth of the carbon pattern and prevents oxidation.

Will the carbon fiber yellow over time without a clear coat?

Unprotected carbon fiber can yellow when exposed to sunlight. Clear coat acts as a UV barrier and keeps the weave looking fresh. If your grille sits in direct sun regularly, protective coating is especially important for maintaining that crisp carbon appearance.

How do I seal the edges once installed?

Sand the cut edges lightly to smooth any roughness, then apply a thin coat of clear to seal them. This prevents moisture from wicking into the weave at seam points and keeps the edges looking finished. A single pass with clear is sufficient — no special edge sealant is required.
