I have owned a log home in southern Vermont since 2007. The house was built in 1989. The stain on the house seems to be in good shape and I would like to keep it that way. I have not put anything on it since I purchased the house and I do not know what the previous owners applied. A local log cabin builder/restoration business is pushing a product called Transformation Stain. Have you heard of this and is it a good product to use? Thanks.
