If you want a wood item to last any amount of time in the elements, this is great stuff to use! It really does soak in to the porous part of the wood and seal it from water. It'll help paint stick a lot better too. For maximum protection of wood, I use a coat of straight epoxy set onto the green cured CPES, then follow that with paint. At that point that wood is NOT going to rot!
Great for treating and sealing wood - Doors, Garage Doors. Wooden Boats, window sills, shutters, out door wood furniture. Must be covered with Paint or varnish.
