which glue should i go for with glueing a sheet of aluminium to the rough side of fibreglass? preferably one thats cheap in bulk as i suspect i'll need a fair bit of it.

Aliminium to GRP?
Make sure you rough up the aliminium surface first (makes a huge difference).
You could use epoxy (it'll stick to dry polyester GRP and ali nicely). I'd shy away from polyester as you'll likely just get a thin film that will delaminate.
That would be my choice (unless you're gluing shed loads on in which case it'll get a bit expensive). You could mix in some micro balloons- otherwise if the back surface is bumpy you'll end up with quite a thick overly-strong layer of epoxy.

'Gripfill' Bonds just about anything to anything, you will probably not get it off again!

ta lads, will look into it, its just to reinforce my dash before i fix it down as its wobbling all over the shot,

thanks again

Tiger sealer / Sikaflex / or any pu sealers
sand the ally first

if it needs to be stuck good and proper, drill loads of small holes into the alli
