Basically in mine, I opened up a green metal texture and then drug a picture of rust into the same image (creating a new layer) and did some erasing of the rust to let some more paint show through. I did some other minor stuff like brightness and contrast, etc...but outside of that, it was pretty simple. Let me know if you want the .psd or hell even the .jpg file if you want to play around w/ it. MD PS...I like the effect Drac had in his too.
