Ditto above sentiments- The proper closing of a hood has always been to drop it and use it's own weight to latch it (well, since the 70's, when my Dad showed me how to do it, plus any competent mechanic I've encountered), whether it's made from steel, aluminum, or kryptonite. Once you know the height to drop from (no higher, no lower) for your particular vehicle, Bob's your uncle.
It IS possible to close the hood by pushing on it (even aluminum, you could do it 1000 times without denting it) but you MUST push in an area, usually around the edge, that is supported from underneath.
Sorry to hear this story - better to try and fix the dent sooner than later, the longer you leave it the longer the metal (and paint) will have to take a "set" which will make it more difficult to do a neat job. Also, do it when it's warm, but not so warm that it softens the paint. Be careful of scratching the paint, too, of course.
IMHO - aluminum is THE way to build a quality automobile. The more aluminum in a vehicle, the better, and aluminum is no stranger to Ford, who has been using it variously in production for more than a decade and a half. The use of steel is illogical, but it's cheap. Titanium is ideal for many applications, but its price is kept artificially high by political protectionism left over from WWII. When that changes, (a lot comes from China now) and the price becomes set by conventional market forces, it will the next logical metal for use in cars.
The new 150 leapfrogs Ford wayyyy above the competition, who will now be scrambling to do the same thing to catch up...
