I've not personally built salt water caps - the performance is inferior
to polypropylene MMC's, are bulkier, messier, etc. But I don't believe
salt is a problem with corroding copper. It may corrode the aluminum
foil over an extended period of time, but this won't directly impact
performance, and you'll probably trade up to a poly cap before that
happens. Salt water caps are quick and dirty. If you want something
that lasts, use polypropylene MMC's.

With saltwater caps like you suggested, how big of a problem is
corrosion? I know I've seen suggestions to use copper sulfate (sold
as a root killer for septic systems, etc.) as the salt, but that seems a
bit expensive. So is there anything you can do to manage
corrosion in normal saltwater caps?
