I'm only interested in blind riveting, if I can get to the back, I'd rather weld.

Is the use of adhesive only for sealing, or is it meant to add structure? I'm not sure if I trust glue, I'm having enough trouble trusting rivets.

So what about using self-tapping screws instead? I'm not sure if anyone's done this, but would there be any reason not to use them?
