I watched all of your videos. The realism achieved with paper is staggering. For example the door at 3:02 not only has a true metallic gloss but there are subtle bulks in the underlying structure too. I will be making some paper fighter models and I wonder what kind of color you use? Do you apply primer spray and coats or is there more to it? Do you know of any good tutorials for this type of advance paper modeling on the net?
