hey fellas i was just in true value today and i saw that they had copper flashing for roofs. The offered it in huge rolls for 50 bucks a pop. Thing is that they offered small squares of the aluminum sheeting witch was not very malleable. So my question is does anyone know where i can buy smaller pieces of copper flashing so that i may use it for making head gaskets? even a small roll would be fine if it was less than 10 bucks or so.
