Mesh would resist fluttering in the wind somewhat, due to it being open. Also solves any heat build up problems.

But how much would it shape airflow? Is it really almost as effective as a solid smooth surface? Or is it closer to having nothing at all?

I though about strategically placing holes in a belly pan to try release pressure differential.
