OK Guys here is one on dope finishes on the balsa models that I use. On the smaller models the thin balsa 1/6 tail surfaces tend to warp because of the shrinkage when using butyrate (Fuel Proof) dope and also will blemish/come off with the 35% fuel. I use the nitrate dope that does not shrink but is not fuel proof. After I do all of my painting, sealing and trimming I put on 2 coats of the Monocote Lustracoat. It is fuel proof and has limited shrinkage and goes over the nitrate quite well. After sealing the wood with the Nitrated dope and sealing it with the Lustracoat I have experienced no warpage on any of my small models and no fuel damage to the finish. Try it you will like it!!
