Steve,
Here's a quicker (time wise) solution to checking materials for corrosion.
Take a large plastic container of water and add some rock salt (like we use
on the ice and snow here in New England-or in water softeners in San Jose
hi). Not too scientific but it works.
Just put the hardware in the solution and see what happens. If it rusts out
in a week, look for better hardware! You could also add some stainless
steel hardware at the same time just to use it as a time gage. It shouldn't
show any changes.
