I was well aware of the issue when we had our 09 flatbedded down from michigan 5+ yrs ago, its still got 4 miles on it, never been driven - ever. I poked thru the paint under the hood hem on the brand new car the day I got it, it was powdery white underneath. just wanted to confirm wether it was crap that wasnt cleaned or corrosion. the corrosion was there from day 1.
I oiled the little hole I poked, the little blisters havent spread yet, but the car never gets wet. before I ever drive it, Ive decided right or wrong to clean/seal the hem edge with 'automotive goop', its messy, but has enough toluene to melt into the paint securely, then tape up the hood(off the car), pour or inject a liberal amount of ospho phosphoric acid and roll the hood around coating the inner perimeter with the acid, then rinse well with water, again with alcohol, then one edge down at a time shoot some heavy paint inside, tilt so it runs the length of the hem, let dry, repeat one edge per day till its sealed...I might not be around in 20 years, but hopefully the car will, and will still have a unblistered hood.

seems silly? I tore my new 06 apart before it ever got dirty and sealed every seam that wasnt properly sealed(drivers rear had missed spots all around the shock mount) injected paint into all the downward pinchwelds, used truck roll-on bedliner in the rear wheelwells and the front unibody structure with the hood/fenders off, poured paint inside the door bottom hems... a weeks labor, but the car is a U-Boat underneath- still looks like new at 60k underneath. the wifes 07 she didnt want me to tear apart, it just gets washed, and at 20k looks like most well maintained cars underneath, but not like new, a few little spots of surface rust showing at things like controlarm seams, etc... not mine

our 65 galaxie hood has original caspian blue enamel, no blisters, shines a mile deep. my 69 mustang hood has no blisters on its Acapulco blue paint, but its old paint is checked, will be stripped. my 2000 merc has original paint, car has rusted away bad, will be junked after this winter due to frame rot, but the hood is perfect. my sons 98 ranger, other sons 2000 expedition ave perfect original hoods, only my 3 mustangs have had ANY crappy hem work. dummy me didnt do anything on my 06 hood, as I knew it was aluminum, and *assumed* it wouldnt matter... didnt take much time to learn aluminum oxidizes faster than steel- at least this crap does...only aluminum Ive ever worked with was 6061-t6, it looks great forever.

I just dont see how anyone can defend the bad processing of the new mustang aluminum hoods.
please go back and look at the auto show pics- ford has still not got a ear to the ground a year later. I really hope competitors start showing their quality- if hyundai had a commercial that said -"look at our panel finishing, then go look at your ford" fords market share would drop overnight- and deservedly! it just stupid that this simple issue noone else has has not been fixed a decade into it.

mark my words- if that all aluminum F150 is slapped together like this it will be the end of Ford. they CANNOT let their best selling moneymaker fall apart before its paid for and ever expect to sell another. too much of our economy is riding on the few remaining manufacturers here... guess the 'big three' dont have to include ford forever...
