There's a branch of plywood boat construction called "Constant Camber" which is based on special sheets of plywood with a mild dish shape. They are then altered about and twisted as usual in hull construction, but they give much nicer shapes.
One item on my to-do list is fender skirts in molded fiberglass, and once I have a mold, getting more parts is just a matter of motivating me. Maybe I'll make a very generic mold, producing panels that could be trimmed to fit many different cars. Already, my basic plan is to improve the looks by overlapping onto the body considerably, to smooth the transitions and create nice new lines, instead of hacking into a given arch feature.
