Sounds like the .03 dia aluminum wire probably wouldn't last very long. I have
a bunch of rolls of copper coated mig wire for steel welding
that is also .03 inches dia. Others that have tried this stuff found that it
rusts very quickly, what a shame you can get 1000 foot rolls of this stuff
pretty cheaply, sigh................. I read from other posts is that
electric fence wire works pretty well and is not that expensive either.
