That's basically what I had in mind, overlapping panels that move up and down with the control arm. Think: Big fish scales or bird feathers, overlapping like roof shingles. Thin coro. oughta flex pretty good.
T-shaped supports might not be needed if you slip some skinny wood dowel rods of correct size into the coro. flutes, where needed.
On the coro, if too close to a hot spot from exhaust, etc. put some aluminum foil tape on, which both reflects heat and dissipates it, alu. being an excellent heat conductor. ~$3/roll at hardware store
UV not a problem whatever, under the car. Coro. is, after all, designed for outdoor realtor and political signs.
Again, the reason I like white is cuz you can easily see and trace leaks or seeps. Instead of just some dark wet spot in the dim recesses of the engine bay, you can see green coolant stain, red brake fluid, brown oil, etc.. Wipe off with sponge, so next time you look you know if it's a new stain or not. Also helps when you drop some washer or nut Lord knows where down there.
