Oh. That's your problem right there. It's supposed to go "steel is real".

As for fasteners and such, if there are still any old-school hardware stores the didn't get washed away, they're a good source for stainless steel fasteners. Both my local ServiceStar and Ace carry metric hex cap screw. All my bikes have all stainless fasteners. Still, I use anti-seize on them as well. That should go for your seatpost too.
