I use a calligraphy nib attached to aluminum tubing to apply Tenax or other liquid glue. Not only does the glue flow like ink out of the “pen,” but I can reach hard-to-get-at spots and put the glue exactly where I want it. Now, I keep a couple of different nibs at my desk. You can find them at specialty pen and stationery stores.
