Where do you Buy Your Sheet Metal?

Thanks again for all the help everyone! I found a shop here locally called Jones Sheet Metal; the owners name is Woody and he was very helpful and let me dig through their scrap pile and sold me a nice sheet of 18ga that will be enough to finish my whole car for $18. Said I could come by anytime! They also make patch panels there for simple auto body repairs; there was a guy who walked in with a piece of bent up wire and said: “I need this bit about 26” long!” Very nice people who gave me exactly what I was looking for!
Perfect!
