Help me keep track of metal and rust techniques

1. Basic metal: Base with Leadbelcher then wash with Nuln Oil (optionally and Agrax Earthshade and / or a second Nuln Oil ) then highlight with Stormhost Silver .
2. Heavily rusted metal: as basic metal, but before highlight use Typhus Corrosion around the model and liberally stipple on Ryza Rust .
3. Rusted metal: as basic metal, but before highlight use patches of Seraphim Sepia and stippled Ryza Rust to add corrosion.
4. Bronze/brass:
5. Worn/veridgris Bronze:
6. Gold:
7. Scorched metal: Paint rings of Drakenhof Nightshade , Druchii Violet and Seraphim Sepia successively along the weapon barrel/exhaust pipe. Use Lahmian Medium to thin the paint if you're doing a large flat area.
