I'm planning to use some galvanized steel spike-nails for an outdoor project. I'd use seven inch nails and Nine Inch Nails* for the project, but I can't find them in odd sizes. So, my idea is to buy ten inch nails and saw them down to the desired lengths.
The catch is that sawing the nails would leave a large surface of steel without the galvanizing. Without the protective zinc, will that bare steel rust?
I know from chemistry that any zinc that's electrically connected to iron should protect the iron through cathodic protection, but does practical experience match the science? In other words, will the bare iron rust even though it's not supposed to?
