I'm building a 10ft x 10ft hunting platform and want it to last for a very long time. I have seen the new Red colored pressure treated lumber at Home Depot vs the old green treated stuff. I would assume the Red stuff is a safer version. So my question is for my 2x6 plank decking would this Red treated wood outlast Redwood? The price differnce isn't much and I don't need the nice finish of redwwod. If it was redwood I assume I need to clean and stain it every few years which I don't want to do either.
