A friend of mine wants me to build the wing in this photo for his F100.

Would you make this as a single flat sheet with a cosmetic layer followed by several layers of heavy cloth, or, 2 layers of Carbon, PVC core, and 2 layers of carbon? Hardware is on him to figure out. Just talking the layup.

Deadline is August for a 250 mile rally run up a highway.

Sorry couldn’t get the pic to load but here is the truck:
