Red / Weathered Rust style for industrial and Sector Mechanicus terrain as transcribed from 'How I Paint Things - Sector Mechanicus & Necromunda Scenery' by Sonic Sledgehammer Studio (https://www.youtube.com/watch?v=QvfbpvbtoOs)

Priming

1. Prime the terrain with Chaos Black

Highlights

1. Dry brush Mournfang Brown relatively liberally across all of the model
2. Dry brush Necron Compound on metallic areas such as floor grates, ladders, bolts, etc. Note that Necron Compound is a rather bright silver and may cause too much of a 'clean' contrast if applied heavily. Consider a more subdued highlight with a darker metallic like Leadbelcher or similar

Panels

1. Apply un-thinned Burnt Red to paneling. This can be stippled and applied unevenly to enhance the deterioration effect
