Aluminium Rust Treatment - cheaper than half price ?

[hartley]

Just paid £550 to have slight bubbled paintwork around door handles removed and 2 doors resprayed - immaculate finish - cannot tell the difference . The job involved removing the door linings and the drivers side lock. Thoroughly recommend
'chips away franchise ' .
Wonder how that compares with Aston's price when they offer ' to pay half ' as a gesture of goodwill ( because they did not paint it properly in the first place ) ?

Aluminium does not and cannot rust.. it can corrode however :-)

Though isn't the paint bubbling due to other imperfections or contaminants?

Good price to have it rectified though. I have used Chips Away also and always had good results and PERFECT paint match.

+1 on both these counts

Aluminium oxidises just as iron does, 'rust' is just a colloquialism.

The process is the same for both metals, although iron is more reactive

Lewis, where would we be without your useful insights

Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide FeO(OH)·Fe(OH)3.

oh oh, I sense a chemical stand-off, this could get interesting....as unlikely as it may seem.

I had mine done under warranty in June 2012, the car was just over 4 years old at the time (and under extended warranty) and i didn't pay anything at all.

What does aluminium oxide consist of then? It's basically the same but with ally replacing the iron molecules isn't it?

Highly unlikely - me being interesting! As Mr Gould said I am a (IT) Geek. Did remember from my days as a Scientist playing with Nuclear Subs that technically rust only applies to iron.

Had to use Wikipedia (so it is probably wrong )for the:
Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide FeO(OH)·Fe(OH)3.

The main difference is that Aluminium's oxidation protects the metal with a coating rather than destroys it... And going back the other way, Aluminium metal is produced from the Aluminium oxide; Bauxite is the ore, Corundum the crystal form. Corundum can manifest as Sapphire, and when a certain shade of red, Ruby.

They both oxidise rather than both corrode but Neil is right, the term 'rust' is correctly only applied to iron and its alloys. But it's a pretty loose scientific term.

I wasn't arguing!

And after all, you were the one who told us the Cygnet would save Aston with its low emissions and so on. And look at them now, selling tens of thousands of Cygnets and making rafts of all-new cutting-edge cars to universal approval

Hurrah for the Cygnet, and its champion, Neil

Nope different valency so it give AL2O3

Yep hence anodising!

[hartley]

I stand corrected by the geeks - where would we be without them .

It still chews up your car though and previous threads suggest Aston are reluctant to do more than offer a contribution which in effect is no contribution because they over charge . Good to hear someone got their ' oxidisation problem ' sorted for free.
Chips away to be fair pointed out that whatever you do the problem can return - something to look forward to !

Pity AM didn't offer to go halves with corrosion problems on 1970's V8s ! They'd have gone under even more times.
