So I have decided to do the area between the front pan and rear axle with screen that is glued and screwed in place.
in process and after ...
With all of the screen in place I painted it with a couple layers of paint with a roller and have sealed 1/2 or so of the holes.
Tomorrow or soon I will hit the area with under coating.
Next the area from the rear axle and back bumper. I think Lexan will be the best answer there.
Wind noise is reduced .
The car also feels "lighter" and only slightly a bit darty. Could be my imagination or simply different road surface influencing the driving feel.
