......because of its transparency it is necessary to hand select each piece of wood used for color,grain,unwanted out of scale imperfections etc.....
With this station /passenger car I have lots of leeway with the wood but remember that at one time this was a functioning RR car, so I will build it aged but some of the original car will still be there.When I get to building Morton's luxury car when using various hardwoods ,I will have to be much more careful with both the miniature carpentry and wood finishes.
OK so now we have a lot of stained wood of various wood tones and grays.Now we will have to decide whether or not to take the weathering process a little farther at this point or not.If you will always have easy access to the wood like on the outside of a shack wall ,go ahead and use it as is, but if it is inside in a confined area you can take it a few steps further at this time.
(With this method no airbrushing is required and the methodology is very forgiving of mistakes.)
Get an old toothbrush with stiff fine bristles,then mix up a very thin wash of raw umber and water.Raw umber is best for this step as it makes for a nice representation of mud flecks,fly sh.t etc...Dunk your toothbrush in the mix and flick off most of the contents onto a sheet of paper with your thumb.When you get down to a very fine spray then flick it on your work ,either board by board or section by section that you are working on.If you have prepared your boards properly it with instantly sink into the wood and dry very quickly.Keep doing this until you are satisfied ,and remember some boards that are close to the ground may require a gradual change in intensity top to bottom.Later some may even require a little mossy green were they come in contact with the ground.
