I am trying to find anyone familiar with this product. It was recommended to me by a vendor of pressure cleaning products but I have yet to find anyone who has used it and knows of its performance and longevity. Davlour Coatings.
Sorry, but we have never used it.
Maybe it's a product you should review.
We can look into it. It sounds a lot like the Wood Tux by Extreme Solutions. We tried that years ago with decent results. It applies to damp wood and last about two years. It did darken some in color. I would reach out to them as well. Maybe they can offer some advice.
