I have one and I love it for olive oil. You can't fill it all the way to the top because the pumping that you do to create the pressure needs some "head space" inside that center cavity. Otherwise, you get a tiny little spritz and not nearly enough pressure. I hated it until I figured out I should only fill it about half full, but it lasts a really long time. I imagine you'd have to really water down the glue but it could work out well unless the glue clogs the spray nozzle.
