Does this need clear coat protection after I paint it?

Yes. After applying your base color, a clear coat layer will protect the paint from UV fading and environmental wear. This is standard practice for any exterior body panel and keeps your finish looking fresh long-term.

Can carbon fiber yellow or degrade without UV protection?

Carbon fiber itself resists yellowing, but any paint or clear coat finish exposed to direct sunlight will fade over time without UV protection. A quality clear coat applied after your base color is the best defense against color shift and oxidation.

How should I seal the edges before painting?

Sand the edges smooth and apply a thin epoxy edge seal or filler to any exposed carbon weave before priming. This prevents moisture from wicking into the material and ensures a clean paint line. Let the sealant fully cure before sanding and priming the entire panel.
