I am just now getting around to restoring the deck that I partly destroyed last year in order to build my shop.
The old (about 25 year old) western red cedar 2x6s have (mostly) stood up very well and I can re-use most of them. Right now, I am sanding them down, then I will use Sikkens deck stain on them. But, I am encountering a few places where rot has resulted in some holes (see the attached picture). It possible, I would like to plug these holes an re-ruse the wood. In most of these places, the repars can go on the down side of the board so no one will see them so something that is ugly (e.g tar) is probably OK. I would just go ahead and use roofing tar, but I thought that there might be something better and less ugly.
