Does this come with clear coat, or do I need to apply my own?

These arrive uncoated. Clear coat is highly recommended to protect the carbon weave from UV exposure and maintain gloss over time. Sand and prep the surface before applying your chosen clear coat system.

Will the carbon fiber yellow or fade without protection?

Unprotected carbon is vulnerable to UV yellowing. A quality clear coat acts as your primary defense against discoloration and keeps the weave looking crisp for years. This is especially important for exposed outer panels.

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

Once installed, gaps and edge seams should be sealed with flexible trim sealant or gasket tape to prevent water intrusion. Apply sealant before final clear coat if you're coating the panels yourself, or use weatherproof trim seal after installation.
