The weathering was many steps.
- Rattle can spray silver
- Airbrush darker gray in random areas
- Dull Coat everything
- AK Heavy Chipping fluid on largest trusses (after spraying a rust color first)
- Vellejo Light Rust Wash over everything
- With a natural sponge and heavy body acrylic, dab on rust on various colors
- Create rust streaks using oil paint and a fan brush to swipe down
- Bragdon Soot and Grimy Gray colored weathering powders
- Assemble
Simple as that!
