Has anyone tried putting some kind of panel behind the rear seat to minimize buffetting? Two things that lead me to think this might work to improve the comfort of rear seat passengers. First, when hauling leaves in the wayyy back behind the back seat once I hit travel speed they started blowing to the front in a whirlwind flurry and filled the front passenger floors. Second, alot of the high end convertibles (MB, BMW, Porsche, etc) have just such a panel that comes up when the top is down. I picture a nicely finished nylon sheet w/ pockets all the way around that would fit around a frame made from some conduit.... Thoughts?
