Automatic Weathering Aircraft Paint

I am not a programmer or a painter, but I have been impressed with want is possible from all of the talented people involved with this hobby. Would it be possible, by using XML gauges, to monitor the amount of time an aircraft is flown, and possibly weather (rain, snow etc) and over time have the texture of the aircraft look weathered (i.e. dirty). In addition over time the exhaust areas would become dirtier. Then with the push of a button, have the aircraft back to its clean look. Just a thought.Jim
