Does this need clear coat after painting?

Yes. After applying your base color, a clear topcoat protects the finish from UV exposure and road contaminants. This applies to any painted trunk panel, regardless of material.

Will the carbon finish yellow over time without protection?

Carbon fiber can fade or discolor under prolonged UV exposure without proper sealing. Applying a UV-protective clear coat immediately after your base paint will preserve the finish and prevent yellowing.

Should I seal the panel edges before installation?

Yes. FRP edges are porous and absorb moisture. Seal exposed edges (seams, cutouts, fastener holes) with epoxy or automotive sealant before final assembly to prevent water ingress and edge delamination.
