I would look at the reasons people give. See if they
really have sound logic or whether they're just repeating
something they heard. I'm in New England. Lots of weather
extremes. I just don't see the rusting of galvanized nails
that people talk about. Our deck here is almost 20 years
old. PT 4/4 x 6. It's not the most elegant wood, but it's
held up fine. I've also used solid oil deck stain (which is
hard to get now).


At 20 years old, it is probably the old PT wood, not the current stuff. Required
fasteners are different.
