Like I said, I very much like some of their products, but I think that this one, is not the best. 9 months of protection? Not likely. And me and about a dozen other users still cannot see a difference when it is applied. I think that Sal has been doing such a good job over the years that he could put anything in a bottle and sell it and people would rave about it on here. I am not in anyway saying that is what he is doing here, but just using an analogy.
