A mix_shader is used to layer two different standard_surface shaders. We will use one standard_surface shader for the top green paint layer (green) and another standard_surface shader to represent the exposed metallic surface underneath.

• Create a 

• Connect a noise shader to the radius of a curvature shader (bias and multiply will work too). Experiment with different noise settings to get the look that you want. Don't forget that you can connect a color_correct shader to the noise shader to further refine the appearance of the 'worn' look.
• Connect the curvature shader to the transparency attribute of the layered shader. This will control the blending between the two standard_surface shaders.
