I 2nd Merv's experience. My on the ground
radials, on an oceanside salt marsh, have
held up as new for 4 years and I used the
lead free plumbing solder. The only issue
is that solder requires a bit more heat
then the leaded solder.
That's all I use outdoors any more.

My original 29 radials were all soldered with lead-free electronic solder and they are all fine after 2-3 years. I didn't do anything to try to protect the soldered connections -- everything is fully exposed and lying on the ground.
