No pictures of the back, so presumably just the skin without any stiffeners ?

Anyone already got one ?

It looks like it is purely a skin, so either needs fitting to steel stiffeners or fitting with pins/straps.

Here it is on the Magnum site

Putting this onto steel stiffeners will cause electrolytic corrosion problems if you do not ensure that the steel and aluminium are not properly isolated from each other. I would say the is only suitable as a completely removeable panel with pins and/or straps.

The original special tuning bonnets were built up with various steel and alloy components bonded and riveted together. No significant corrosion issues if done carefully.

All aston martins had a Steel frame with alloy skin.
If done properly there shouldn't be any issues...

Proper Astons corrode never buy one.. reason is unpainted steel during original build .. most certain my past DB24mk3 was full of the white stuff also had a Aston BBS6 that all i could do was cut off the full side elevation of that body shell to hang up on a wall :roll:
Probable the Magnum Alloy Bonnet Skin would be ok bond to the steel underframe with suitable product that would also act as a seal between differing metals

To get electrolytic corrosion you don't only need dissimilar metals in close contact you also need an electrolyte, i.e. salty water.

With the amount of salty road action that most of our Minis see, there is little or no danger of this in 50 years or more.
