The screen on the carbon fiber model is black. It will help keep debris out like Lupe noted, but will not keep out water. While driving, this is not an issue as water is unlikely to collect in any one place due to the movement of air over the vehicle. At a standstill, water can collect to an extent, but there is a slight upturned lip where the screen is molded in which will force the water to pool slightly before it goes anywhere.

Water dripping down into the engine compartment at that location isn't a big deal. Lupe has been driving around with his fiberglass prototype of the hood for months now without issues, even through the recent rains we endured.
