Everyday objects~Anyone using any for aero?

I can attest to the marginal usefulness of the rubber molding/trim I found at HD. You can see a piece I used on the front of the hood in the garage. It looks a little wavy there, but not bad. But when I attached some to the back end of the hood, for wiper cowling, the curve of the hood really put some waves in it. Attaching it to a straight edge would be okay. But compound curves are too much for it.

It doesn't look great, but at least it has the wiper arms out of the wind. And looking across the parking lot at work, I see wipers and arms in full view on everything, even the Prius. All I can see on Porthos is two little bumps sticking up above the cowling.

I'm hoping I can force some better shape to it when we have a hot sunny day (soon! soon! please!) Or perhaps I'll build a rigid one some day, like Autospeed.com's.
