The way you are describing it, though... the channels sound like something I could fab on my own with a little fiberglass as an add-on to the underside. I wonder if anyone has one of the said $$$ hoods that I could take a look at locally...

Not really worried about moisture, I just like the idea of not immediately having a filthy engine compartment every time I get caught in the rain.... point taken about defeating the purpose though. It will take some thought.
