The question is how to seal all the the wood parts to prevent warping. Resins are too hard to sand and they obscure the wood look and feel. Water based glues allow warping right away. Whatever sealant you use may react with the finish paint you use. These questions go on and on and on. Feel free to augment or change the title to correctly ask this question. My ultimate goal is to be able to use a combination of paints, powders and pan pastels after assembling the kit using any combination of adhesives to do the assembly.
