The vents in stock location are for low speed/ idle venting of heat from the engine compartment. The "turbo" vent pulls air in to cool the turbo location when the car is moving.
For venting under hood pressures, I'd use the fender vent idea as to avoid the high pressure from the windshield. But the high pressure under the hood is mainly from the firewall. I would assume vents closer to it would work better.

I've down loaded it but have yet to test it out.
I would guess that they are describing gravity like a you would a vacuum. Air does not get "Sucked" in to a lower pressure area. It gets Pushed from a Higher pressure area.
POR-15 is Durable from what I hear. I have also been told it does not hold up to UV, and would need some form of top coat.
BTW, it also comes in silver.
The sheet metal should hold up fine as the oven only get to around 400 F
As with ANY tool, inspect what you buy before hand. I don't care who's name is stamped on it, I check it out before plunking down the cash if I care if it lasts.
One class, ouch. How hard to finish it? Maybe school loans to living on for that time?
Can't help much otherwise. I'm looking for a full time job helpdesking or such. Good luck.

I'm not sure where they are made, but my dad's is basically 3/4 bridgeport and has held up very well so far. 10+ yrs.
The S130 hatch locks are pretty light duty IMO. The parts looked pretty flimsy to me when the lock smith around here took mine apart to fix. Luckly they aren't hard to take out, kind of a pain to put back in.
