 For a real long time. I mean, if it gets direct sunlight, you're going to get three years out of it. But you don't have to do any prep except just clean it and then put another coat on there. So I don't even see the need to come back and put a clear protectant over it. I just use an exterior. If you want a stained look, I would just use an exterior house stain and be done with it.
