Because the implied claims I saw for great fuel economy on the Thermo-Tec box in the Autozone seemed misleading. Unicorns often exaggerate plausible results for marketing advantage, like a horse with a horn, or that can sprout wings and fly! But maybe this thread should be moved by moderators. I'd support that.

Agreed. And so, the questions. Thanks.

I didn't. It's about appearance. Only top side is painted. Why worse?
And thanks for the link. The civic has a cover, but I would bet it could be improved.
