[QUOTE="thill, post: 496014, member: 4972"] The new ACQ and copper-based PT wood is nowhere NEAR as durable as the old PT. Very often, it is made using a terrible grade of wood to begin with. I am NOT thrilled with it. On jobs, we spend the small fortune to pay for ground-contact versions. This is another reason I seal the wood, including PT, with Thompson's. Everything is made cheap nowadays. For what it's worth, my Princecraft is SYP plywood sealed with Thompson's under carpet, and it's holding up great. Not sure how long, maybe 6-7 years, now? I'd have to check my tinboats.com posts from years ago. Fuzzy, that boat has blue carpet inside. Doesn't help with moisture, that's for sure! I've heard that the newer chemicals are not as reactive with aluminum, but I wouldn't trust it, especially when I can lay a sheet of house wrap down and not have to worry, and it has the side benefit of keeping the foam dry. That is a win-win situation if I've ever seen one! [/QUOTE]
