Will the carbon fiber yellow or degrade if exposed to UV?

Carbon fiber itself is UV-stable, but if there's any exposed resin or clearcoat finish, UV exposure over time can cause discoloration. Apply a UV-protective clear coating or store the seat indoors when not in use to maintain appearance long-term.

How do I seal the edges of a carbon fiber bucket?

Sand any exposed edges smooth, then apply a two-part epoxy resin or automotive-grade clear coat to seal them. This prevents moisture absorption and protects the layered carbon from delamination. Let cure fully per the product instructions before installation.

What's the mounting method for this seat?

Mounting hardware and method are not specified — you'll need to confirm compatibility with your vehicle's seat rails or plan custom fabrication. Test-fit before committing to mounting fasteners.
