John Welsford recommened this product to aid in rot protection. I did a search on the internet and found no links to the good ole' USA. Anyone know of a supplier or simular product? It is supposed to be used on initial construction to aid in rot protection. This product has the viscosity of water, so it penetrates easily and has a fungicide. Then it is paintable when it dries. We are talking a plywood lap construction. I am trying to avoid encapsulating with epoxy, although epoxy will be used as a glue (typical Welsford procedure).
