Weathering was pretty straightforward. I used various panel line
washes depending on the tones and the effect I wanted to
accomplish. I also used a few filters using white, brown and blue
oils by placing tiny dots of paint on some of the surfaces and then
brushing them lightly with a brush moistened in white spirit.
Oil and gas stains were created by using a little Mig Fresh Engine
Oil effect, brown and black chalk pastels, and white spirit. Drops
of this slurry were placed on the model and a clean, dry airbrush
was used to blow if around just as the airstream would in flight.
One last point I want to mention is that not a single drop of
varnish was used on this build. I was able to achieve a really
beautiful, patina-like finish by buffing the model with a lint-free
paper towel that I purchased from a plastics supply store. Buffing
had the advantage of actually wearing off paint from raised areas
such as screws and hinges giving them a subtle, but realistic
appearance.
All in all, this was an enjoyable project that resulted in a beautiful
model without the use of a lot of after market items.
