Should I apply clear coat before or after installation?

Apply protective clear coat before mounting. Sand and prep the surface lightly, then lay down a UV-protective topcoat to preserve the carbon weave and prevent yellowing over time. This also makes future cleaning easier.

Will the carbon fiber yellow in the sun without protection?

Carbon fiber can discolor under prolonged UV exposure if left unprotected. A quality clear coat acts as a UV barrier and keeps the weave vibrant. Plan to reapply topcoat every 2–3 years depending on your climate and how often the trunk is exposed to direct sunlight.

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

After installation, use weatherstripping tape or automotive sealant along the perimeter where the panel sits against the body. This prevents water from collecting between the carbon fiber and the frame, which can lead to corrosion on mounting hardware over time.
