Your best bet is a dull or satin spray lacquer, like Deft. As soon as you get the first coat on, poke it with a paintbrush to clear any bubbles made by the rough bark. Within a few minutes, spray again, and again a few minutes after that. For the last coat, turn the twig at odd angles to be sure you got into all the crevices. It should last years.
