Yes. And that space between the two extrusions gives the chassis some character and keeps it from looking like a "dull and boring" slab of metal.

It depends on the texture of what you're gluing and if you're gluing metal and don't use a super hot glue (or heat the metal) you'll get a crap bond. If it's two smooth surfaces, crap bond.
