I do it the same way you described. I use a dental syringe to meter the glue exactly where I want it and cover every joint. It gives you a nice glue line and not too much. Works really well. You can get them for next to nothing at a med supply place. I have a box of them, and when I fill it, I tip it upright to get the air out, and store it in a cup of water to keep it from plugging the tip up. Works great and makes for a really strong joint.
