Does this need clear coat protection?

Yes. A UV-protective clear coat is strongly recommended to preserve the carbon weave and prevent oxidation over time. Sand the surface lightly and apply your chosen automotive clear coat system following standard prep procedures.

How do I seal the edges after installation?

Once fitted, seal all panel edges with flexible automotive caulk or polyurethane trim sealant to prevent water intrusion and protect the exposed weave. This is especially important at the latch points and where the panel meets the rear body lines.

Will the carbon fiber yellow or fade without protection?

Carbon fiber can oxidize and lose clarity without UV protection. A quality clear coat applied during installation will maintain the finish for years. Regular washing and occasional wax will keep it looking fresh.
