CWF-UV from the Flood CompanyAll Wolman products for deck and fenc staining.
Stay away from all Thompson's Products.
I do this in part for a living and I do like CWF-UV. It does last a good two years. It does penetrate the wood. It comes in many stain colors. It is applied with a brush.
Any stain that is applied from a deck pressure wand is generally not that good. If you have to brush it on, then it is generally good.
Remember, these preservatives are not a one time shot. You will have to do this every two years or so. The first time the wood will soak up an enormous amount, then this begins to equal out.
