Call me jaded, but anything called "Lifetime" well, whos lifetime? Especially talking about timber frame exteriors. I wonder what the weasel words are on their products?.
Interesting. Note that it is a treatment, not a finish. I read somewhere that the only reason they need the P in PT is because they treat it green; if you applied the same stuff to dry wood you could get just as much penetration without the pressure. My guess (and it is just that) is that that is pretty much what this is. They had to change the formulas for PT a few years back to be non toxic. Still guessing here but I bet it is similar to Tim-Bor.
