So now that you guys have all theorized about how good this product is i have been applying this product for the past fourteen years and even though this line of discussion is dated probably id like to add my two cents worth to the topic. Now as you have pointed out with the uv protection that the pigment would tone down over time and make the boards succeptable to damage caused by the uv greying the wood out over time. The appropriate way of application ensures that it penetrates the cellular structure and actually fills the pores of the wood. There is not really a color to it other than a very vague tinge of the cedar oil. and the greying occurs over time not so much from uv damage but dirt and grime being on the surface of the wood. Not from damage being done by the sun. I always recommend to my clients that they take their garage washer and a little deck brightener to the deck annually or offer to include it as an annual maintenance program i suggest to my customers. If your worried about the uv and want to apply a stain over the top of the petriwood you can and i also recommend it as a pretreatment to my clients as once again it has filled the cellular structure. So the wood doesnt swell with the humidity as it cant penetrate it, the warranty protects you from cupping cracking and twisting so when it is applied it makes the wood more solid to put it into laymens terms. My stain jobs last alot longer than if i dont use it and i have had stain projects last upwards of 8 years on vertical surfaces as the boards dont expand and contract, so the coating applied doesnt have the substrate swelling up or squeezing so the coating is not damaged by the substrate it is applied to just the limitations of the stain itself. Also bugs hate this product, I applied it to a clients wicker patio furniture and you should have seen them come running out of it. Also ice doesnt form on it and that is pretty big if you live in south dakota, also that green slime on the north side of the house cannot grow on it. The silicone in the product is actually silane solution which is used to seal concrete on a regular basis and as you know you can stain concrete after the sealant has been applied. So that being said ive been using it about 14 years and it is a wonderful product and recommend it to any and all professional painters, and wood finishing pros out there. As far as the utility poles they are recommended to be treated prior to install by a dip tank process. and the application of the product for us deck guys is to apply the solution until it cannot be absorbed into the substrate any more usually two coats with a diaphram sprayer or bug sprayer you can use an airless but i suggest a seperate one for the petriwood because when it and water meet it starts to gel up and will harden in the material lines if you clean it out with water fyi. Hope this helps yall and you can add tints to it just has to be a powdered tint. Thats all the info i got for you guys to absorb. I hope it helps and yes it does work like it says I applied it to my fathers decking about 14 years ago no rot replacement of wood or dryrot on any surface to date every year i give it a wash and it still repells the water like it did when i first applied it.
