If it is touching the dirt and is in direct contact with soil and moisture it will corrode at some point. I know that, I was just wondering why baseball bats don't corrode. Also, if I can use the AZT line for mounting to gutters. Better safe than sorry, so I'll stick with copper, brass, bronze. Okay, after I made my beer run last night, I read through Moyer's section on fixture materials. I am now looking for a platinum fixture with a plastic coating, which will hover an inch above the ground. On a more serious note, I also read about the salt crystals in the air which are very corrosive to aluminum. I am convinced I will stay 100% aluminum free. This includes bottles over cans.
