Do I need to apply clear coat after painting?

Yes. After painting, a clear coat layer protects the finish from UV exposure and maintains gloss. This is standard practice for all automotive topcoats. Apply per your paint manufacturer's specifications.

Will the carbon fiber yellow or fade without clear coat?

Unprotected carbon fiber can discolor under extended UV exposure. Clear coat seals the surface and prevents yellowing. If you choose to leave the Raw FRP finish exposed temporarily, store the trunk in a covered area when not in use.

How do I seal the edges where carbon fiber meets the factory hinge?

Before final assembly, sand and prep the mounting surfaces on both the panel and hinge area. Once painted and clear coated, the finish will seal the exposed edges. If gaps appear after installation, fill them with body filler, sand flush, and topcoat to match your finish.
