Does this come with clear coat, or do I need to add it?

Carbon fiber is delivered uncoated. We recommend applying a UV-protective clear coat to preserve the weave finish and prevent oxidation over time. Sand the surface lightly and apply your chosen clear in thin, even coats.

Will the carbon fiber yellow or fade without a protective coat?

Unprotected carbon is vulnerable to UV yellowing and surface oxidation. Clear coat provides a moisture and UV barrier that keeps the weave looking fresh. Plan on sealing it during installation.

How do I seal the cut edges where the grille meets the frame?

Sand the edges smooth, then apply epoxy or clear coat along the perimeter where carbon meets the mounting tabs. This prevents water intrusion and protects the resin from weathering. Let it cure fully before installation.
