Deckman, you do know they have stain that is the color of "natural wood" right? Stuff works great! My buddy JJ used it on his deck and I never even knew untill I dropped somthing and you could tell it had a coat of somthing over it. Maybe you should give that a try.
Yes there are some kind of stains/coats that not only keep the natural color but it enhances they way the wood looks. I personally like to have a brownish wood for my deck and when applying this stain over it, it gives the wood a bright brown color with I love.
