Does this carbon fiber trunk need clear coat?

Yes. Clear coat protects the carbon weave from UV damage and fading over time. Sand and prep the surface before applying your chosen clear coat system for best adhesion and gloss retention.

How do I seal the exposed edges after installation?

Carbon fiber edges are porous and will absorb moisture if left bare. Seal the perimeter with epoxy resin or a carbon-specific edge sealant before final assembly. This prevents delamination and keeps water out of the weave.

Will this trunk yellow or dull without protection?

Carbon fiber itself resists UV yellowing better than fiberglass, but clear coat can still degrade if exposed to direct sunlight for extended periods without protection. A quality clear coat and periodic detailing keep the finish crisp and deep. Consider a UV-protective ceramic coating or regular wax for maximum longevity.
