I'm not a fan of "one-size-fits-all" scale modeling solutions. And this ties into what appears to be an increasing common trend among modelers, namely, that there should be a commercially produced solution to each and every modeling challenge. You see this in all those "Where can I buy a 1/7 scale X" questions. Why would anyone assume that ONE color would do for each and every WWI aircraft that had a "clear" dope finish?
