To all who have wooden boats and don't like the tedious job of varnishing, there is a product that is much easier to use and in my opinion produces a better result. It's called water based polyurethane. It comes in an outdoor version with UV inhibitors and it does not amber. It dries in about five minutes, so dust settling is not a problem. It also is available in gloss, semi-gloss and satin.
I am a woodworker and have been for more years than I want to think about. Over the years, I have tried many, many different types of finishes. Water based polyurethane is the best, easiest, toughest, non-ambering finish I've ever found. In particular, I prefer the Varathane outdoor.
