Will this clear coat yellow or need UV protection?

Carbon fiber does not yellow like exposed resin, but your clear coat will. Use a quality automotive clear with UV additives during your paint process to keep the finish looking fresh. Proper prep and a quality two-stage paint job will protect both the carbon and the topcoat long-term.

Do I need to seal the carbon edges where it was cut?

Yes. Carbon fiber edges are porous and will absorb moisture if left exposed. Sand the edges smooth, then seal them with epoxy resin or a thin coat of your primer before painting. This prevents water infiltration and keeps the structural integrity intact.

How does wet carbon compare to dry carbon for this trunk?

This trunk is manufactured in dry carbon—lighter weight and faster production. Wet carbon typically offers a glossier finish out of the box but adds weight and cost. Dry carbon requires paint prep and finish, but delivers the weight savings and durability you're after on a performance trunk.
