That's Joe's way of building his models. Every modeller has his own way and his own type of finish. Joe's models are immaculate, I could never find anything at fault with either the building, or the panel lines or the paintwork or the finish, in my humble opinion perfect. However, he does not like to weather his models at all. That is his way. each to his own, its just a matter of preference, like building a tiger tank fresh out of the factory. You cannot say one model is correct and the other isn't. I envy him and wish i could at least once obtain such a finish. Still, i prefer some weathering but that is my way. If you are going to start building planes, and you seem to be having one hell of a time doing that, and you are good at it too, you need to find your way and the finish you prefer.
