Peter's method of waterproofing his planes applies to all foamboard planes. It covers the ragged simi-peeling edges of creations that makes our planes stand apart from commercial produced models. Provides solid base for painting and gives more durability. It allows for integration of other materials as for turtlebacks (rounded tops on fuses) out of insulation foam and cowlings. The general idea is not new as similar technics were used with elmers glue. After covering two fuses and one wing I am sold on the idea. Using white paper instead of brown paper may not be as strong??? but it gives and easier base to color. Too much paint (weight) can change the flying characteristics. The more people try this method, the more refinements will popup. It's the difference between building a plane to fly and building a flying model.
