OK, good enough, if that's the standard, I guess I shouldn't mess around trying to figure out if it really is necessary in my case.
Now I need to redo some nailing I already did with standard 8d common nails 4" o.c., between the 1/2" struct one plywood and the PT 2x6 sill plate. Would it be a problem to interleave corrosion resistant 8d common nails, yielding a 2" o.c. straight nailing pattern?
Thanks, Wayne
