Clear urethane cracks after a few years. I've seen it too many times. After that you're stuck with it. Water gets in the cracks and turns the oak black which really looks nasty. the only thing you can do is to try to grind the whole mess off and start again. I used Watco teak oil then Man o' war spar varnish and steel wooled between each of 6 coats. It came out beautiful. I protect it with a tonneau cover and park under a carport because I don't believe there is any finish that will protect wood from direct weather. Just my .02
