Don't know why that didn't turn up in my original search, but very helpful in understanding the possibilities, and of course includes posts from Aerohead and Aeromodder!
I was trying to find some tall plastic wastebaskets with rounded edges as material for fender fairings, but the tall-enough ones are pretty pricey. Maybe I'll cobble a couple together. I've found the material of the Rubbermaid or other quality brands to be excellent for shaping, in that they already have useful radii and can be cut and manipulated easily. Easier that buying and forming aluminum.
