Vertical 4-panel grid split, showcasing four distinct aged painted surfaces. Top panel: smooth deep-green enamel paint over metal with subtle orange-peel microtexture and soft controlled specular highlights. Second panel: sun-faded exterior paint showing fine crazing, chalky oxidation, uneven color fading, and exposed primer beneath the surface. Third panel: severely peeling paint with curled brittle flakes revealing multiple historical layers of cream, blue, and rust-red coating beneath. Bottom panel: heavily deteriorated painted steel where cracked coating has fallen away to expose corroded metal, orange rust, dark oxidation, and mineral deposits around the damaged edges. Macro detail photography, directional side lighting emphasizing layered relief, physically believable coating thickness and material boundaries, ultra photorealistic., Trigger Words: real_surface
