If you are "filling" the wood with your product I am curious how Ready Seal would work. I have used Ready Seal in the past and while I am being fictitious it seems you could put Ready Seal on a cedar board and catch some going through the underside it is so penetrating. If you change the characteristics of the wood how is the sealer supposed to work as it should? Secondly, Exterior Wood Restoration and building a business is about maintenance and building a customer base. If the maintenance and future coats of this product, or any other, are not future maintenance friendly then they aren't worth it. Third, ALL customers want 2 things, protection and appearance, bottom line. This should be addressed in any coating. Honestly, from your post it sounds like any penetrating product would not work and what I posted previously about film forming products is what is best after these treatments have been applied. Perhaps someone more versed with Ready Seal like Pierce, Diamond Jim, or Pete would jump in here as well. After looking at the website it looks like it is a silicate or "silica gel" that is used. In my opinion, you will get VERY FEW wood guys that will use this product or agree with you on this being a good product to use. At the end and I personally have not been sold on ONE of these products.
