Does anyone use Sharpie Poster Paint Markers for marking their queens? I've seen these, when doing internet searches for paint markers that might work well for queen marking, especially since they are water based, acid free, opaque paints, and come in, "white", "fluorescent yellow", "fluorescent blue", "fluorescent green", and "fluorescent pink". I was hoping to find someone who has already tried these markers and has some experienced input. I've been using the Uni-Posca markers, and they work quite well, but thought the fluorescent colors might be even easier to spot in a crowded hive.
