Should I apply clear coat to protect the carbon finish?

Yes. A UV-protective clear coat will preserve the weave pattern and prevent yellowing over time. Sand the surface lightly and apply your chosen automotive-grade clear coat per manufacturer instructions for best results.

How do I seal the edges where the trunk meets the body?

Use automotive weatherstripping or sealant along the perimeter where the trunk panel meets the body line. This prevents water ingress and maintains a clean appearance. Prep the mating surface and follow your sealant's cure time before closing the trunk.

Will the carbon fiber weave pattern be visible?

The 2x2 twill weave is part of the design — it's visible under clear coat and adds authentic visual character. If you prefer a smoother finish, sand the surface before applying primer and paint of your choice.
