Do I need to seal the edges where the carbon weave meets the frame?

Yes. Sand and prep the surface, then apply your chosen primer and paint. Once cured, seal any exposed fiber edges with clear coat to prevent moisture infiltration and UV damage to the weave.

Will this yellow over time without protection?

Clear coat is your best defense. Carbon fiber itself is stable, but UV exposure without a protective topcoat will gradually dull the finish. A quality automotive clear coat applied during your paint process will preserve the gloss and color for years.

How does wet carbon fiber differ from dry?

This panel is built as a standard carbon fiber component. The visual difference between wet and dry weave is purely aesthetic—both are equally durable. Your choice depends on the look you want after primer and paint.
