You live in Florida and your Mustang is only 5 years old and it's Rusting! I'd be MAD as hell with FORD! Or is it that problem they had with 05 and 06 Aluminum Hoods Corroding? In any case it should have never happened. Sorry to hear about it. I'd be on the Phone with FORD no matter how many miles were on it.
They kinda have you by the Gajonies with this one as it's not Rust, your Stang probably has more than 36K and is past the Warranty, so they win and you lose......Bad......

My 2005 Mustang Hood...

is also rusting from the inside out. An auto body company told me that this happens to most of the alum hood mustangs. When I showed them where the paint was bubbling on the hood, he showed me where it is rusting from the inside. Of course I contacted Detroit and was told it is out of warranty on the corrosion and paint. I am super upset and beyond mad.

um....trade it in and go get something else.

Without pissing you off, I would like to help you out so you don't keep running around telling everyone your aluminum hood is rusting. Aluminum can't rust. It can oxidize very badly...but can't rust (Rust is Ferium Oxide, Ferium is Iron and Oxide is the oxidation of oxygen).

Aluminum oxidizes just as iron does. We just don't call the results rust. And the results of iron and aluminum oxidation are quite different. When iron combines with oxygen in the air to form iron oxide, otherwise known as rust, the result is destructive in that the rust weakens the iron. When aluminum oxidizes it forms aluminum oxide which forms a protective coating on the aluminum which helps prevent further oxidation.

With all that being said, if you choose to keep your car and change the hood. I personally have a Cervini and love it. Would recommend that brand any day of the week.

EVERY mustang Ive seen has it to some degree- including my undriven, 4 mile 09. it was poor prep at the factory, starts out looking like a little seam sealer under the paint or something- its not. *if* it starts to spread (when IMO) it goes fast- I kept my 06 (never salted/summer only) waxed under the hood, the little 'seam sealer' spots were the same for 2 years, then over a few months time, spread to 3" wide, up over the top surface.
I put a Fang/Aeroform shaker on it, like the look, but its heavy as heck. its a shame they didnt prep most of these aluminum hoods right, its a nice lightweight piece.

I hate to mess with a undriven new car, but am thinking of masking/sanding/etching/epoxy sealing the edge of the 09 before it gets driven, along with injecting thick paint, tipping the hood down till it seeps thru then taping up...I did this to my 06 when new, to all the unibody pinchwelds(wife kinda freaked when she came out in the garage and saw a new car all tore apart... fenders/doors/etc...) but every oilchange I wipe down the undercarriage and other than staining of the exhaust, it looks like new underneath... the wifes 07 has hints of rust in places like the seams of the lower control arms, k-member seams...mines mint so far...probably spent 20-30 hours sealing everything except the lowest drains, but its a u-boat underneath

on the 09, sitting inside it hasnt changed in the >2 years Ive had it, but know how fast my 06 blossomed into a pitted mess...being a aluminum hood it was the ONLY part I didnt fill/seal. DOH!

heres what I replaced mine with...Fang/Aeroform shaker

I am an aircraft mechanic, and we face this problem every day. Corrosion is a problem with aluminum and magnesium, which most airplanes are made of.

When a surface gets corroded bad enough, the only thing we can do is replace it. The corrosion on airplanes, and our hoods, is commonly known as Filiform corrosion. It will eventually, if left untreated, eat a hole in the metal. We normally will strip the paint, clean the corrosion out mechanically (using Scotch Brite or similar), treat with Alodine to restore the protective coating, then re-paint. I haven't checked into how Ford does things, but I would be willing to bet they don't use Alodine, but use some other cheaper, easier to use protection.

About all one can do is replace the aluminum if they can't put up with the corrosion, because it will likely continue forever.

back in '89 I made a r/c heli frame set from 6061, got a alodyne kit to treat it...had a clear acid, then a brown dye, left kinda a irridescent gold tint on the aluminum.

when you are doing aircraft parts, can you use alodyne on assemblies? I assumed you'd need to separate the parts to seal/rinse them- just wonder if the stuff you use today is the same as the oldschool stuff. I'd like to save my original hood somehow, but really didnt think there was any way to stop it shy of 'uncrimping' the top panel and removing all the crap that started it, between the crimp seam... if theres something out there that can creep back thru the corrosion and seal it off, that would be handy.
I just think cleaning the exterior surfaces only wont stop a thing, and kinda doubt the top skin could be removed without trashng the hood. if theres something out there for aircraft assemblies, would love to hear about it

Not trying to thread jack here but does anyone know of a company that makes an aftermarket hood that weighs close to or the same as the stock hood? The thing that sucks about all these cool looking hoods is they weigh more than the stock hood. Its going to be hard to beat the weight of an aluminum hood but I'd be happy to just get close if possible.

absolutely right - bad prep, not selead seams and thin paint as also not a good primer on the alloy thats the reason why this happens.

I god a new hood under warranty last year for my 2007 GT vert.

My hood problem started out slow and then suddenly got worse this past year.

Of course I drive mine year round through Chicago winters, so I guess it's to be expected that it might spread more quickly as time goes on.

I'll be getting a Cervini hood and a painted superstripe now that my tax refund is coming in (and is bigger than expected:yup.

Also be sure to check the seams at the bottom of your doors. Mine has the slightest little bubbles by the door seams. You have to remove those plastic plugs Ford puts in the doors at the bottom. Crap gets stuck in there and the doors don't drain right. Hopefully it will be a few years before that becomes a major problem
