In the near future Im going to be buying a new paint booth and, well heres my question. Which is the best material to use for air lines? Cost is not a factor since galvanized, iron black gas pipe and copper are all pretty close. The copper has the advantage of being able to bend easy and once sweat soldered should stay together forever. The black gasline pipe is after all made for air. Most people Ive talked to advise me to go with the galvanized, claiming superior strength and durabity. So, thought Id get some opinions here. Thanks, Al
