I have made the same statement on this Forum many times. And unless you are in a contest, most people you show the model to, don't know a DR I from a SPAD. Models are like baby pictures......Did you hear anyone shown a baby picture say " That kid is really ugly " !!!
Having spent 20 yrs in the military, I can tell you that most examples of weathering I have seen in models are extreme. Any bare metal is "spot painted.......so I laugh at models with bare metal showing. And on a carrier plane....the salt would cause rust in minutes.
It would take a year to fade the fabric on an a/c as much as some modellers do.
