Heavily worn and damaged metal panel surface with dark tones and advanced signs of decay. Features strong rust buildup, corrosion stains, surface dents, and deep grime between seams. The horizontal panels are still intact but clearly aged and neglected. Ideal for post-apocalyptic scenes, abandoned structures, war-torn vehicles, or environments with strong storytelling through wear and material history. This is the final stage in the wear progression, showing full deterioration after long-term exposure and use.
