Does this carbon fiber need clear coat protection?

Carbon fiber benefits from a UV-protective clear coat to preserve the weave finish and prevent oxidation over time. Apply your chosen clear coat after final fitting and surface preparation to lock in the carbon's appearance and durability.

How do I seal the panel edges?

Sand the edges smooth and apply clear coat or epoxy sealant to the raw carbon edges to prevent moisture ingress and delamination. This step is especially important where the over-fender meets existing body lines. Your choice of sealant should match your topcoat system.

Will the carbon fiber yellow in sunlight without protection?

Unprotected carbon can develop a hazy or yellowed appearance with prolonged UV exposure. A quality clear coat applied during installation will block UV rays and maintain the weave's natural black finish for years. This is standard practice for any exposed carbon fiber body panel.
