Does this grille need clear coat protection?

Yes. Raw carbon fiber without UV protection will yellow and lose its weave clarity over time. A quality automotive clear coat applied before installation preserves the twill pattern and extends the finish life significantly. Sand lightly and prep the surface before applying your chosen clear coat.

How do I seal the edge seams to prevent moisture and debris?

The grille edges should be sealed with epoxy or automotive-grade resin before clear coat application. This prevents water ingress into the carbon weave and protects against delamination. Work the sealant into the perimeter during prep, then sand smooth before your final clear coat.

Will wet carbon fiber be heavier than dry carbon?

This is hand-laid carbon fiber construction, which uses resin saturation for strength—not a dry weave. The result is lighter than OEM plastic and rigid enough for direct bolt-on fitment without additional reinforcement.
