A guy at the boatyard the other day was telling me, as I gooped polysulfide all over some stainless hardware
I was bedding down to wood, that he thought polysulfide could corrode stainless. I've *always* used the stuff in this scenario, but it got me googling and I turned up this from the Wikipedia article on Polysulfide:
Polysulfides, as sulfides, can induce stress corrosion
cracking in carbon steel
and stainless steel
????? Can anyone describe this interaction for me? I even scuff the mating surfaces up a bit before bedding, probably removing the passivated layer in the process, I wonder if that could make this corrosion
even more likely?
The poly sulfide products themselves claim compatibility with stainless, so I have to believe that statement on Wikipedia is taken deeply out of context.
