OK, I've seen that one, and he makes some good points, but does not counter the ones i made. I made a velomobile frame, seat, and full suspension from six moldings, myself, and read trade magazines on composites, so I know the potential, as well as the problems. Sheet Molding Compound is replacing more metal every year.
Interestingly, the automotive industry has a slow and expensive way to adopt plastics, because they insist that everything must survive an old-style paint oven. You'd think that the resin formulators would get together and knock down the temperature needed for a quick bake of the finish.
