Re: Wood for transom?
I used to be a residential builder and worked with pressure treated lumber quite a bit. There are different grades of pressure treated and variations in the amount of treatment. Some was more heavily treated for use below grade. If it was not treated for use below grade it would rot in a few years. The problem is, the treatment makes the wood wet. I used to have to paint or stain it occassionally and the finish would not take until the wood was dry enough to allow the paint to adhere or the stain to soak in. I believe this is the concern with using it in boats. The resin will not soak in as long as the wood is too moist. Also, for residential work the pressure treated plywood is generally a low grade, CDX or worse with few plys and lots of voids. It also can warp badly as it dries. In a post last week in the "project boats" section was a link to an article on marine plywood that was pressure treated and then redried. This would be ok.<br /><br />Best regards, <br />RCS
