I'd go with 2 part polyurethane. I did our deck about 8 years ago, and now it needs some attention again. If we had used anything but the 2-part, I'd have had to paint it three times by now. It is a lot of work - you don't want to do it more than you have to. Follow the instructions diligently and use the tech hotline and email helpdesks. It will take longer than you think because the weather will not be ideal. Take a day to mask everything you don't want paint to get on. Then take another day to mask the spots you missed the first time. We still have paint spots where I missed the masking, and the stuff is too expensive to have it go where you don't want it. I used a roller & brush. Spray guns clog in my inexpert hands. You may have trouble leaving it in the water while you sand: State DEP types don't like that kind of stuff blowing directly into the water.
