Does this need clear coat protection?

A UV-protective clear coat is highly recommended to preserve the carbon weave and prevent yellowing over time. Without it, the resin can fade or develop a hazy appearance after extended sun exposure. Apply your chosen clear coat system before installation.

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

Sand the back surface lightly and apply a flexible adhesive or trim sealant rated for automotive use before pressing into place. This prevents moisture from entering the weave and keeps the trim secure. Let the adhesive cure fully before driving.

What prep does the carbon fiber need before installation?

Clean the existing tail light trim area thoroughly and remove any old adhesive or debris. Sand and prep both the mounting surface and the back of the carbon trim lightly to improve adhesion. A clean, smooth base ensures the trim sits flush and stays in place long-term.
