Do I need to apply a clear coat to protect against UV yellowing?

Yes. Real carbon fiber will benefit from a UV-protective clear coat applied before installation. This guards against oxidation and maintains the finish gloss over time. Sand and prep the surface before applying your chosen protective topcoat.

Should I seal the carbon fiber edges where the fenders meet the body?

Sealing exposed edges is recommended to prevent moisture ingress and delamination. Use a flexible sealant rated for automotive paint-to-carbon bonding around any visible gaps or edge lines after installation.

Will these fenders require special preparation before final assembly?

Inspect all mounting surfaces and hardware contact points before bolting on. Clean and lightly sand areas where fasteners pass through to ensure solid contact. Check fitment against your existing fender gaps before final tightening.
