It's a nice thought that I use some kind of applicator that puts a minuscule drop of glue down but I don't. I've tried using a pin or toothpick and even those little detail brushes from Microbrush.
Try using a modified sewing needle.
Take a sewing needle. and grind away the eye end until just the top of the eye is open. Then you have a "U" shaped channel at the end that will hold glue or whatever. There are an assortment of needle sizes, each having its own sized eye.
As an aside, I thought superglue was CA glue.
