I don't like to leave my equipment nice and shiny all the time. alot of it has dirt, rust, and other grime all over it. at the same time, i also model commuter trains, and even outside commuter trains, i always bump into the same problem: How do i "dust" a model? I mean, look at this U23B for example- http://crcyc.railfan.net/wall/trenn/trenn-cr2735.jpg and now here is a picture of my weathered model of the same locomotive yeah, its trucks and pilots are dirty and rusty, but that easy enough to do. if anything, i can probably systematically add more rust to the trucks and pilots, no big deal. the radiators are alittle tougher, as well as the exhaust (especially since my airbrush is out of commission), but i still drybrush some grimy black all over. the problem for me is the rest of the locomotive. those spots on it that don't have the big rust streaks, most of the nose, and the cab, and the long hood lack any real smudges. on a the model, its still nice fresh conrail blue, but in the pictures, its faded, but not so horribly faded, if you know what i'm saying. How do i achieve this look? that look of age, but without blemishes? The same goes for my commuter trains. few of them gleam like they are new, but none of the prototypes, save one or two pictures of some of my U34CHs, have any real rust or grime stains. at the same time, they look dirty some how. look at this GP40FH-2. its far from "new", but where is the weathering? on a model, would it be safer to simply let it gleam? http://www.hobokenterminal.com/alltime/photos/gp40fh-2/njt_4133_gp40fh-2_hoboken_mjs.jpg I hope i'm making sense to you guys, with all this "phantom weathering and stuff". thanks for your advice.
