Resistance to corrosion, yes. Corrosion proof - 100% no.

Iron oxide - rust, brown and flaky.

Aluminium oxide - hard and white bubbles.

Bear in mind, it isn't pure aluminium, it is an alloy, so may not actually be the aluminium that is reacting....

I've seen it start as a tiny spot but also grow across a panel to be a huge "bubble". Unlike steel, I have never seen a hole form!? Which kinda defeats the 12 year perforation warranty......
