Casper- Interesting how the Reich's warbirds can look so sinister. I like it. Sorry to here about the poor fit of the cowl. Still a great job on the E-4.
I've got some weathering pics of the Lightning.
Started by adding oil streaks and stains using a mix of black and brown from my daughters watercolors.
I'd pic up a generous amount of both colors on a brush then apply to likely oily spots. Then with a damp flat brush ,pull the color in direction of airflow and/or gravity.
Also added some streaks with Prismacolor pencils.
Material for the mud stains and general dirt kicked/splashed up around Henderson Field.
I made a dry pastel "mud" mix of various tans and browns. I also added a few drops of dish soap and a couple drops of white glue to the water for a wet wash of mud later . Hopefully the glue will make the pastel wash more permanent .
First a dry brush of ModelMaster dark earth together with the "mud" mix.
Then a wet brush dipped in the dry pastel mix to create a heavy wash. Using the broad flat brush to move and distribute the wash around.
Allowing the wash to dry, followed with a dry dusting of the pastel mix.
I also worked the pastels onto the wing walk areas. I figure the crews would often track mud and dirt to those areas.
Started the exhaust stains working in black and brown pastels followed by tans, grays , and finally a little white.
Finishing up the last fiddly details, and this build will be complete.
