Do I need to clear coat this carbon fiber trunk?

Yes. Apply clear coat over your paint to protect against UV exposure and maintain the finish. Without protection, the painted surface can dull or yellow over time. Sand the primer base lightly before painting, then apply your base coat and clear coat per manufacturer specifications.

Should I seal the edges where the panel meets the body?

Yes. After installation, seal the edges and seams with a flexible weatherstripping or sealant to prevent water intrusion and road debris from entering the trunk cavity. This step protects the interior and extends the life of the panel.

Will this fit without modifying my trunk latch mechanism?

The panel is designed to work with factory mounting points. Verify that your existing trunk latch and hinges align with the new panel before final installation. Minor adjustment of hinge positions may be necessary depending on your specific vehicle setup.
