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

This arrives as bare carbon fiber. Apply your chosen clear coat to seal the weave and protect against UV exposure. A quality automotive clear coat is standard practice for all carbon fiber panels.

Will the carbon weave yellow over time without protection?

Yes — UV exposure degrades the resin over time. Clear coat acts as your primary UV shield. Apply it immediately after final surface prep, and the panel will maintain its appearance long-term.

How should I prep the edges before finishing?

Sand edges smooth with standard automotive sandpaper and inspect for any fibers or resin irregularities. Seal all edges with clear coat or epoxy resin to prevent moisture ingress. Clean edges also look sharper when the panel is installed.
