I am not worried about the corrosion of our A2 Aluminium.
There are three different types of Alu on the A2:
-sheet matal. (doors, roof)
-casting (A and B-section; the mirror part, images)
-extruded aluminium sheath (sillboard ...)
And until now only the cast (not coated) shows the corrosion and it will take a hundred years until it becomes a problem, i think.
But what I wantet to say is, that the corrosion is not oxide, as most people would think. It is hydroxyde and apparently will not end up in oxide. But in the end thats no difference. It is corrosion. But still not worried about even scince one German wrote, that after his accident a lot of white powder was found in the sillboard. I am not shure if that is true.
@ Mark Brigg: You are right. Even painting the Mirror part would have been enough for let them live forever.
And the weight will rise up, if you keep all fallen off oxides. So measuring the wheight is not so easy, for that you have to calculate the weight of added Oxygen. But ok, on Aluminuim you could wash out every powder and measure the weight in the end.
I think the metallic lattice/structure is different (causes the corrosion) on casting aluminium. But other people mean the one small damage on the paint will bring wholes in the sheet metal soon.
I don't beleve.
