Should I seal or clear coat the carbon fiber edges?

Yes. Sealing exposed carbon edges prevents moisture ingress and UV degradation at the weave perimeter. Sand the edges lightly before applying your chosen clear coat or epoxy seal. This protects the structural integrity of the panel long-term.

Will the carbon weave yellow over time without UV protection?

Real carbon fiber itself resists yellowing, but the clear coat protecting it will degrade under prolonged UV exposure. Apply a UV-protective clear coat during installation and reapply every 2–3 years in high-sun climates to maintain the weave appearance and color consistency.

Can I paint over the carbon finish, or should I keep it exposed?

Both options work. If painting, sand the surface thoroughly and apply primer before color coat to ensure adhesion. If leaving exposed, ensure the clear coat is UV-protective and seal all edges. Either approach is valid—it's a styling choice.
