That is a great tip. I had the idea to pre-shape the clear sheet for the windows using heat. Hot water was ineffective, the temperature was too low for that. The sheet requires higher temperatures which only a heat gun or oven can provide, however, I would need a buck like you described to press the piece onto so that it takes its shape. I'm a few steps ahead of this thread and I am amazed at how good this kit looks. Despite those horrible instructions I am so glad that I have picked this one for my friend. Anyway, the cuts do not bother me much. They are like wrinkles on a face, only here they tell there was some work involved in the making and they make the viewer think of what material the model was made of.If that body where made, then sanded, and the radii and compound curves made into plugs from 2 part epoxy, you could water form one of the fenders without any seams on the corners, and trunk lid. That would take this model way over the top.
