Does this come with clear coat already applied?

Yes. These arrive with factory clear coat protection applied to the carbon weave. The finish is UV-resistant, but inspect the coating during unboxing for any shipping damage and consider a top coat of automotive clear if your climate sees extended direct sunlight.

How do I seal the edges where the fender meets the body?

Sand and chamfer the edges lightly, then apply a flexible trim seal or automotive sealant along the contact line before mounting. This prevents moisture from wicking behind the panels. Let any sealant cure per product instructions before driving.

Will the clear coat yellow over time without maintenance?

The factory clear coat is UV-protective, but all clear coats benefit from regular washing and waxing. A quality automotive wax applied every 3–4 months will extend the finish life and keep the weave looking sharp. Avoid prolonged exposure to harsh cleaners or polishing compounds.
