I was wondering what people use to waterproof wood in boats. I am going to put in a could of 1x4's along the side of my boat in order to create an area to hold things. The wood is replacing some rotted wood which was on the boat when I bought the boat. I have looked at stuff like Thompsons, but have used it before on my deck and it needs to be reapplied every year or so and I'm not really interested in doing that. Thanks in advance.
