Just curious when the manufacturers are going to start offering weathering in addition to painted models. That would be neat to see nice weathering on a RTR model wouldn't it assuming it was done well. I wonder if you can pad print realisitc rust blotches. My prediction is that will happen in the future.
When ERTL came out with their freight cars a few years ago they had what looked like weathering on them. It was an overspray of an unrealistic brown color but it migh have ste the stage for future RTR weathered cars.
One of the manufactuers should try it and see what happens. Oops there I go again risking their money :-)
