Does this need clear coat, or will carbon weave protection be enough?

Clear coat is strongly recommended. Carbon fiber is porous and will oxidize and yellow without UV protection. A quality automotive clear coat seals the weave and maintains the finish long-term — two to three coats over your primer and base will preserve the carbon look.

How do I seal the trunk edge where it meets the body after installation?

After bolting the trunk in place, seal the body line gap using a flexible automotive sealant or trim seal. Run the sealant along the top edge where the trunk panel meets the body to prevent water and debris infiltration. Sand and prep this area before applying finish to ensure proper adhesion.

Will the factory hinge and latch work with this panel, or do I need new hardware?

Your factory hinge and latch hardware bolt directly to this trunk — no replacement needed. The mounting points align with OEM geometry, so installation is a straightforward swap. Verify hinge and latch condition before assembly for smooth operation.
