Thanks for the posts everybody!

The tip of a dental probe tool worked better than the toothpick. But it is still impossible for me to get a thin coat. I don't think the match idea is going to work either because the primer starts to get thick and form a skin within 10 seconds or so. The result is that I get globs of primer that stick out above the height of the surrounding paint (I assume that this is what "proud" means). I'm going to thin the primer with acrylic lacquer thinner then try again.
