Do these panels need clear coat protection?

Yes. Bare carbon fiber will yellow and degrade under UV exposure without protection. Apply a quality automotive clear coat after ensuring the surface is clean and properly prepped. This protects the weave and preserves the finish long-term.

How do I seal the carbon fiber edges?

Sand the edges smooth with fine-grit sandpaper before applying clear coat. This closes the weave and prevents moisture from creeping into the panel edges. A sealed edge combined with full clear coat coverage will keep the panels protected from water damage and oxidation.

Will these fenders fit without modifications?

These panels are built to OEM proportions and designed as bolt-on over fenders. Verify that your vehicle's mounting points are intact and free of damage before installation. Minor fitment gaps at the door jamb or hood line may require shims or adjustment — reference your vehicle's service manual for fastener locations and torque specifications.
