One of the foamsmithing questions we get the most is “what’s the best way to seal my foam props and armor?” The truth is that there’s no one best way. We do have some favorites, but they’re unique to what we have available to us and our skill/tool set. In this video we go over all of the basic methods, and some more advanced ones, so that you have a good starting point for your own experimentation.
