Priming wood and metal for painting with regular matt wall paint

[alligatorlizard]

I'm constructing a rather complicated contraption for mounting overhead acoustic panels in a home studio, which I won't try and describe here, but it'll be made using a combination of wooden battens, aluminium angle-iron, and heavy duty L-brackets. I'd like to paint all these with the same paint used to paint the room (Lick Green 07 Matt), but I realise I can't paint that directly onto any of these surfaces.

I do already have some Zinsser BIN, which from what I can tell would stick to all these things, and on top of which I should then be able to apply the Matt paint to.

Can anyone confirm that this plan would work? Or if there's something more suitable than BIN that I should use? Ideally something that'll prime both metal and wood so I don't have to buy multiple products - though of course if it is better to use separate primers for each surface, so be it.

Thanks!

Yes.
Clean off metal with meths and paint with BIN.
Only problem is if you use BIN outside as don't like the cold. Also no good for rust
