I do not know what I will be spraying yet since I am in the research mode right now. I have done some sealing in the past with SW stain and sealer but on a very small scale. I drive around my town a see all of the fences and decks that need cleaning and sealing and there is no one here that does it. A friend of mine owns a lumber yard and has customers ask about it all the time but no one does it. I even talked with a few fence contractors and none of them do it.
