Help on Metallic Texture

Hi i was wondering if any of you guys could tell me how to make a Metalic texture kind of like this.
Thanks ahead of time.

this is not metallic texture - it’s simply paint texture - no any spec, mirrow etc…

I think you’re referring to the weathering around the outside edges. There was a script that did this sort of thing automatically back in 2.49, but I can’t find it at the moment. So, there’s no “auto” way to do this. You’re going to have to UV unwrap the model, export the unwrap to a paint program and paint yourself an image map by hand.
