Does this trunk come with clear coat?

No—the panel arrives raw carbon fiber. You'll want to apply UV-protective clear coat before installation to guard the weave against yellowing and oxidation. This also locks in the twill pattern visibility.

Will the carbon fiber yellow or fade over time without protection?

Uncoated carbon exposed to sunlight will yellow and lose clarity in the weave. Clear coat application is the standard step to preserve the finish and protect the fibers from UV damage. Plan on prepping and coating before final install.

How do I seal the edges after installation?

Sand the cut edges smooth with fine-grit sandpaper and apply the same clear coat you use on the outer surface. This prevents moisture from wicking into the carbon layers. Pay extra attention to any edge where the panel meets the body line or fastener holes.
