Hello Vic, good question. I have sealed balsa with super glue but never by dipping. This may sound silly but I would worry about it soaking up too much super glue and catch fire during the curing/hardning process. there have been times when gluing in a hook hanger that the wood/glue actually got hot enough to smoke, and it stinks, not to mention the burning sensation in your nostrils. also, when gluing up a hanger, I have had super glue soak all the way through the wood from the inside out and glue my fingers to it so I would assume that it would readily penetrate rather deep into the balsa wood. don't know about other more dense woods. Me thinks I will mostly be sticking with PVC when I have time to tinker. I do know that compared to balsa sealed in other ways it really hardens the wood and makes it have a very different sound if you hit it against something hard.
