I have weathered various colored cars with pastel chalks (wet method) and have came out great. This method works great for me.
My question is what colors when airbrushing, (Badger Model Flex Only) do you use to weather black blukhead flats and tank cars. Being I will air bru***hese I want it to be a one time shot at it. Would like a slightly to well used look.
I guess this is why I enjoy the pastel method, mixing various chalks and expermenting with the effects, one has to be zoned in when airbrushing as once its on it there.
The general ruile of thumb is dark painted surface use lighter colors. Light painted surface use darker colors. For some reason that is the way the weathering looks in real life.
