I've searched old threads and seen a few mentioning using alu for the dashboard, which sounds good to me.
I have used 1mm NS4 for the interior panels and, although it's ok when bonded on all 4 edges against the transmission tunnel it just seems WAY
too floppy to be suitable for the dashboard - given there is no direct support behind it...
So what thickness should I be using? 2mm?
I would use the same material for the front bulkhead too - I am not convinced I could hang things like a fuse box off a 1mm panel!
I used 1.2mm on all my panels.
The dash had a radius bent onto the bottom which gave it plenty of strength.
I'm using 1,5 mm on all the panels of my Fury and the same for dashboard, but I'm interested too in the experience of others.

1.2
I also used 1.2mm, covered with camping mat foam and vinyl. Bottom edges were bent over a bar to give the correct radius. Underside panel riveted to
front keeps it sturdy.
Dash back
Floppy only if it is a flat sheet. That would be thick for a car or aircraft wing. If you cannot put in folds just rivet or bond L shaped ribs to the back side. Use car panel glue it will be fine for this. Instant stiffness, cheapness and lightness (bring out your inner Chapman). If you put a few holes in the ribs you can use then as attachment points for wiring or pipes.

For simple stiffening Silkaflex/Tiger Seal would be fine as the dash is (not very) structural. If you want to go up market try this

Or I use Araldite 420.
Neither or these is locust....Tiger seal sticks at a fraction of the price - degrease first
