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.Hey, so I have a 2005 mustang, need a new hood, mine is rusting. Im freakin out trying to figure out what is the best hood to purchase. HELP.
heres what I replaced mine with...Fang/Aeroform shakerHey, so I have a 2005 mustang, need a new hood, mine is rusting. Im freakin out trying to figure out what is the best hood to purchase. HELP.
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.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.
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.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!
from what Ive read(theres a lengthy thread over at:
Hood Rusting On My 05 ! - The Mustang Source - Ford Mustang Forums
and Corrosion of hood - The Mustang Source - Ford Mustang Forums
on this 'becoming common' issue) repairs often dont hold, I think as theres simply no way to stop the corrosion between the crimped panels from creeping back under the paint within a year or so...one guy had his redone three times so far...
