I think there are enough people out there who want weathered items that would be willing to pay for them and finding people isn't the easiest. I have someone at York who I have promised to bring 5 locomotives to each show and we worked out a price that is fair to him and myself. He always sends me pictures and we can go darker or dirtier if I feel that engine should be. So far he's done 50+ steam and diesels.
I would have examples to show a potential client of light, medium, and heavy weathering and they can pick what they prefer and they need to go into it knowing its going to vary somewhat but if they have a particular amount they want then they can specify. I have never been disappointed once in my locomotives I have received. If you hit me up in my profile I may even be willing to give you a try sometime to try out some rolling stock. If the price is reasonable I am all for weathering but some people charge themselves right out of the market or at least my market. I think if you get a few customers you'll find if they like your work they will continue to weather their stuff. To me weathering is what makes the locomotives and cars look realistic. Unless the stuff has just come out of the shop its going to have some dirt on it.
