I swore off tube glue years ago after discovering how well solvent-based liquid cement worked. I currently use Plastruct Bondene applied with a small brush (depending on the type of join). Bonds instantly, no globs or residue. Simply welds the mated surfaces together and evaporates. There is a slight smell, so ventilation is recommended. This type of adhesive allows one to keep the assembly process going, thus requiring less time to complete a model.
