Oldmobile aerotech longtail
I am going to clean up this mess under the car, sc1 aeromod underbody:
The yellow chloroplast had become brittle in 3 years. The white is still good after 7 years. The two engine cooing vents are shown. Some of the belly pan on the left was removed for gas line cooling. Sticks and stalks get stuck in the vents when reversing in the field. You can see where its melted at the converter.
... New coroplast in place, engine vented to inside of front tires, in the clearance holes. Bungees safely underneath.
