You might consider using longerons over the ribs, made of PVC pipe, then pull the plastic sheet snug. Fiberglass or aluminum tube tent poles as used in dome tents would work well, too.

Or, dacron works well, is light and strong, and comes in lots of colors. It is heat-shrinkable, so once you get the envelope over the longerons, you can pull it taught and wrinkle free by holding a hot clothes iron up next to the fabric (but don't actually touch the fabric).

Homebuilt airplane guys have used this stuff for decades, to good effect. Once you get the shape you want, you can dope the fabric to make it waterproof.

I think bending back is OK as long as the distance between the end of the airdam and the pavement is less than the lowest hanging underbody stuff.

Eventually I want to do an undercar venturi so that I can bleed engine compartment air and wheel turbulence into it. Using side skirts.

How much did that flap around?

I'm still trying to determine how solid a boat tail needs to be . .

Thanks

The rationale for the clear plastic things was that I just happened to have those two pieces of lexan.

One neat thing about the lexan things is that they flip down for hood access. They also flip up/down when I decelerate strongly depending on the speed (above a certain speed it flips up).

What, no comments on the orange brake calipers (got the can of paint on clearance and just tried it out FSAG).

I've since found another can of primer grey for even cheaper so that I can cover up the evidence.

Freakin' wife.
