When you are doing sheeting, you can use a stack of magazines for pressure, they will conform to the curve. 8 to 10 will work. I also use sandwich bags, double zip type filled to different degrees with sand for pressure, they conform well also to do sheeting and just pressing parts while the longer curing glue dries. The kit goes together quite quickly, if you spend any time working on it. Just make sure to read the directions twice for each step. You may find the covering takes as long as the stick build. You are building an incredible flying plane there, you are going to love the way it moves.
