ND Front wings

I’ve already ascertained that the bonnet and boot line are aluminium , the front and rear bumpers are “plastic”, the doors, rear wing and the strip between the back of the cockpit and boot lid are steel, but what are the front wings and the panel that runs under the doors between the front and rear wings made of?  They’re non-ferrous, magnets don’t stick to them, but are they aluminium, “plastic” or something else. does anyone know for certain?  Many thanks!

I found this Countryboy - the front wings are aluminium.

Surprised the other part you mention is not steel - does not seem to be mentioned in the link.

Hey thanks for this country boy, whilst I knew the bonnet and boot were alumindium, I didn’t know the front wings were made of  ‘ali’ too!

Thanks Rhino and ThontonMark, your posts were very enlightening!

In this document, the term “Rust Proof Steel” is used for many components. Are there any details as to the nature of this material?

  

Yes, I agree it’s very intriguing and further info would be invaluable.
