The weathering debate has got to be the atomic bomb of modeling topics.
I've been modeling since 1976-77. My real career has gotten in the way now and then, like all of us. I've always tried to learn. I remember going into the old Ace Hobbies in Manhatten in the 80's, used to go in every time I was working in town. They had a large display case of models that were at a level I had never seen before. These were armor models in 1/35th scale that looked real. And I mean real. I've always held myself to that standard, and will never forgot that place or experience.
I write professionally. In writing there's a saying that fiction is the stylized rendition of reality. I can tell you if it's not, it doesn't work commercially.
For a military scale model to appear as reality it needs something more than just paint. Auto or F1 models can be extrememly clean and still look real. Military models not so much.
So anyone should be able to do whatever they want to do. There are very few color photographs from WWII to help us. I try to stay accurate, but I am not a rivet counter per se. My BR-52 is stylized from one example in a museum, theres nothing to confirm the camo was used in the war.
I'm now completing the large Revell A-400. This is a new aircraft that is very clean. In order to achive some level of reality I'll have to do something to it. A wash of some type, otherwise it will look like a very detailed well built toy. This would be different than weathering a Spitfire after it flew a week of sorties in 1941.
Overall aircraft are a totally different weathering beast than that used for armor, for obvious reasons too long to list. Aircraft, Armor, Ships....were talking apples, oranges, and bananas.
I try not to go overboard with weathring, but have at times.
As long as you're having fun and keeping yourself to your own standards of excellence, wherever that is, then you win. Unless you are commisioned by a museum etc. then accuracy would become much more important.
I consider myself a master modeler and realize that I'll never stop learning or getting better. However realize that almost none of the products that are available today existed for the modelers that created those models at Ace, all those years ago, that are the benchmark of excellence I continue to aspire to.
