Would 3mm aluminium sheet be suitable for rear firewall?,
 

Thinking of using this, with maybe a strip brace riveted down the middle, to seal up the boot area.

Is it thick enough? Or will it wobble like mad.

isn't it too thick? I'd aim for 1.5mm myself :)

Also, what are you trying to achieve? Just "random bits from the boot entering cabin", or a liquid / vapour barrier?

The latter is much more involved, but there's someone on 22b.com who does cnc cut kits: http://bbs.22b.com/forums/showthread...ight=aluminium

That kit looks pukka as far as I'm concerned. Wish he did a new age one :)

Liquid/vapour barrier. I've PMd that guy, as I've no glass in it would be a grea time to do it. :thumb:

Cookstar this is my fire wall its a lot thinner than 3mm plus its had strengthen folds formed into it,its also shaped to fit over the side panel ridges so no need for a seperate panel to be welded underneath just gives you an idea what can be done ,,,have you had a look at Arch's composite panels ???

That looks spot on mate, did you are that yourself?

I think I saw something a while back about Archs panels, but not for a while though.

Fraid not cookstar it was done by the firm that prepped the shell.

I think I'm gonna go with the kit from the guy on 22b, its ready to go and I'm short on time.
