Do I need to clear coat this after painting?

Yes. Once you apply your base coat color, a clear coat protects the paint from UV exposure and road debris. Carbon fiber panels benefit from full paint coverage and clear coat the same way OEM panels do—it's essential for durability and finish longevity.

Should I seal the edges where the carbon weave is exposed?

Sealing the edges is a good practice to prevent moisture infiltration and protect the resin from UV damage. You can use epoxy edge sealant or wrap the edges with primer and paint as part of your finishing process. This step extends the life of the panel and keeps the weave protected.

Will this yellow over time without UV protection?

Unprotected carbon fiber and resin can fade or yellow from prolonged sun exposure. A quality clear coat applied during your finishing process provides the UV protection needed. Keep the panel in shade when parked when possible, and maintain the clear coat with regular washing to preserve the finish.
