Let's take the classic Uzi for example. I know the handle and grip are made of a polymer/plastic so they would be non-metallic but how about the other parts of the weapon? I know any edge wear that reveals the actual metal material underneath would be metallic and always assumed the 'painted metal' on top is non-metallic. What would the painted metal be in this case? Is there ever a case where a metallic paint would be used(for certain car paint jobs etc?). Would colored anodized metal be metallic or non-metallic? Thanks heaps in advance.
