DB9 - Aluminium rust ?
Discussion
Aluminium oxidises just as steel does, so yes, it 'rusts' though the results are different in appearance.
The problems occur on DB9s where steel and aluminium are juxtaposed like the door handles and the side strakes, it's called a galvanic reaction, and the results aren't pretty. Not much that can be done, it'll either affect your car or it won't. I guess some have better paint than others keeping the metal apart, but if the two metals touch, they'll bubble.

Just noticed some bubbling under the paint next to the drivers door handle. Never seen it before - looks like rust bubbling under the paint - aluminium rust ?Anybody had anything similar in the same position.
Oh bugger - I have just noticed mine is going in the same place. Have you contacted AM or your dealer yet? I also have it in the bottom front corner of both doors.hartley said:
Thanks guys - I'll ask the dealer - do we get a 10 year anti corrosion warranty on Aston's ? What a sickner - it's a 2006 and absolutely faultless until now
yeah, its "anti corrosion" ...not paint bubbling on composite material that cant rust ...leaves a big woolly areausually it seems people get offered that they can pay 1/2 of the respray costs...at dealer/works prices ....so 4x normal cost to start with
good luck with it, let us know what your dealer says .....

Mine too, sent pics to the dealer, just waiting to hear back. Seems it might be worth banding together over this?!silverspeed said:
...or is every car coming up to 4 years old vulnerable? ...
Owners will tell us next year I guess

...My 7 year old VX220 never had any paint bubbling and that was painted composite !!
I'm not 100% sure it's the composites...I wonder what's behind the skin in this area? Metal brackets with different materials used...?My 7 suffered from bi-metallic corrosion quite badly eventually (when it was something like 10yrs old). It'll probably need doing again at some point, but probably much later in its life hopefully as I use it far less than I used to and never in crap weather.
I've had a quote incl. assistance from AM...just need to check how much an indie shop would charge. Like bogie notes, I suspect about the same amount...though the invoice would have AM logos on it which would probably look better in the file.
I had this problem on my 2005 Tungsten Silver DB9 at the join between the rear wings and the roof. Although the car was out of waranty, AM resprayed the affected panels under the anti-corrosion waranty. However, they only covered 50% of the £1000 bill. Seems to be the norm for older cars.
