So I cruised Home Depot for materials to skin the wing and the two that I liked the most were Astro Turf or some other outdoor carpet, or that roofing stuff that is black plastic with the fake gravel imprinted into it.
What I was looking for was a thickish material that would bend in a tight radius but not be elastic.
I have the wing about 95% designed and almost all of the materials picked out. I will try and use scrap plywood that we have lying around here but will need to buy mounting hardware. I am planning on using 1/4-20 all the way around.
The first drawing is of all the pieces together. They will more or less snap together and then be secured with wood glue except where the spoiler mount meets the spoiler and the trunk.

The second drawing shows the various angles of attack that we can adjust the spoiler to. It goes from 0 - 35 degrees of attack.

The last drawing is of a concern of mine. I worry that the spoiler will hit the roof when we open the trunk. Alan. Could you provide me a side view picture of the trunk open so that I can gauge our clearance?

I estimate that the without the skin, the spoiler will weigh between 10 and 15lbs.
