A comment about the finish. not the glue. As I am sure you will find out, if you have not already, Epifanes Poly tends to be highly recommended for outdoor projects. It is common to use a fair number of coats to build up protection, especially UV protection I think. Epifanes is often put over a Penetrating Epoxy like Smith’s. Both Smith’s Clear Penetrating Epoxy and Epifanes are marine products commonly used on boats. (The epoxy works pretty well for restoring wood that is beginning to rot as well as being a preventative coat.) I would try these products on a piece of the same wood to see whether you like the result before putting it on your product. You want to check for color changes in the wood and for the attractivness of the funish. The result is not really all that attractive — very plastic like — especially if you do all the coats recommended of the Epifanes. I never tried just using fewer coats. That will be less plasticy but you will loose UV protection. Oh, one other thing, some folk recommend soaking the feet of an outdoor project in the Smith’s to keep those feet from soaking up water. I have never done that but will probably give it a try for my cedar outdoor table which is not aging wonderfully!
