Never hear anyone talk about how the fasteners themselves have changed though. Back when we buttered everything, everybody was still using ring shank nails with the little rubber washer, and they held way better than what passes for roofing nails now. I been on a few tear-offs where the newer galvanized smooth shanks just rattle loose after a season of freeze thaw. If you ain't buttering those boards, at least make sure your nail gun is set right and you're using the good fasteners, not the cheap bulk box stuff.

Idk @the_ray, I've been lucky and never had an issue skipping it.

Heard almost the same thing from a guy at a truck stop diner in New Mexico. He pulled up some old government report on his tablet about weather modification experiments from the 60s. Got me looking into it for a few weeks, crazy how much stuff is out there once you start digging.

You know a buddy of mine who runs a ready mix plant? He said the same thing about fiber after they poured a county road near his parents' place and it's outlasted every mesh job they did before it.

Oh man I found a can of blue paint from 2002 still worked great!
