The PF looks excellent. In regards to rat piss. Reminds me of a trick my Dad uses. He had a pile of lumber infested with rats, worms, ants and other rodents pissing away in a stuffy shed for years. He got a hold of a huge plastic bag, loaded the wood in the bag and threw in a crap load of germ, scent, pest smoke bombs. Sealed the bag air tight and let it sit for a few months. That stinky lumber is now the wood paneling for our cabin. The bugs made really interesting textures to the panels and the stank is gone.

That's for Mousin' Around!
