Does this need a clear coat, or does carbon fiber come protected?

Carbon fiber benefits from UV-protective clear coat to maintain its finish and prevent yellowing over time. Apply your chosen clear coat after fitting and any final surface prep — this is standard practice for exposed carbon and ensures longevity.

How do I seal the edges so they don't fray or absorb moisture?

Sand the edges smooth, then apply a thin coat of clear epoxy or resin to seal the raw weave. This prevents moisture wicking and keeps the edges clean. Let it cure fully before installing.

What prep is needed before installation?

Sand and prep the mounting surface on your factory fender to ensure a clean fit. Verify clearance with your wheel and tire setup before final fastening. Refer to your vehicle's service manual for any fastener torque values.
