I have 2 yellow cedar slabs which I am making into outdoor benches. I want to make the benches done with a clear that will last as long as possible. They will be placed outside all year including harsh winters but under a covered deck. What should I use?

Thompson Plus Waterproofer Plus Clear Wood Protector | Exterior Waterproofing (http://www.thompsonswaterseal.com/waterproofing-products/waterproofers/waterproofer-plus-clear-wood-protector) is a great product but nothing will guarantee that the wood color will not gray over time.
