This is the problem with PT lumber. You have both the wood moisture plus the caustic chemicals added to it. I let any of my PT lumber sit in the old barn for a yr or two before touching it.
Correct me if I'm wrong but, isn't Turtle wax an auto wax? I see this all the time in the auto sections of any store.

"Whether active duty, retired, national guard or reserve - is someone who, at one point in their life, wrote a blank check made payable to "The United States of America", for an amount of "up to and including my life". That is HONOR, and there are way too many people in this country who no longer understand it." -Author Unknown
