Does this clear coat protect against UV yellowing?

Yes. The clear coat applied at manufacturing provides UV protection to preserve the carbon fiber's appearance. Store the panels out of direct sunlight before installation, and the finish will resist yellowing under normal outdoor exposure once mounted.

Will the panel edges need sealing after installation?

The clear coat covers the visible surfaces. If you cut, drill, or sand any edges during fitment, those exposed carbon areas should be sealed with clear coat to prevent moisture absorption and edge delamination. Your installer or a local shop can handle edge prep if needed.

How much lighter are these than the factory fenders?

Real carbon fiber is significantly lighter than OEM steel fenders. The exact weight savings depends on your specific factory setup, but hand-laid carbon construction delivers noticeable reduction in unsprung weight with no compromise to durability.
