Do these fenders come with clear coat, or do I need to apply it?

These arrive in raw carbon fiber. Applying a UV-protective clear coat is recommended to maintain the weave appearance and prevent yellowing over time. Sand the surface lightly before finishing with your chosen clear coat system.

How do I seal the edges where the carbon meets my body?

The edge seams should be sealed with a flexible automotive sealant or trim-seal adhesive to prevent moisture and debris from collecting underneath. This also helps lock the panels in place and keeps the finish clean long-term.

Will UV exposure fade or yellow the carbon fiber finish?

Bare carbon fiber will naturally yellow with prolonged UV exposure. A quality clear coat applied during prep acts as a barrier and keeps the weave looking fresh. If you store the vehicle covered or park in shade most of the time, yellowing will be minimal; regular washing also helps maintain clarity.
