How do I treat aluminium oxidation on body panels?

Question

Like most of us I have dealt with steel rust on many occasions, but how should I deal with aluminium corrosion bubbles under the paint?

I have just bought my first aluminium car, which are becoming a lot more common now. The bonnet has a few stone chips which have started to bubble.

On a steel car one would sand back, use a rust treatment (krust for example) and then fill / paint.

But How should I "Kill" the aluminium oxidation?

Answer 1

Same as steel panels, only if you use wire disc on angle grinder, use a softer brush. Everything else the same.
