I bought this HW35 new in the late 80’s or early 90’s. It was very dark and had a muddy color that covered the grain. It is also Turkish Walnut. I decided it was time for a stock restoration. After removing the old finish and gently sanding to 500 grit the stock was so slick it would not take stain. I only use dyes in desperation. They penetrate so quickly that they can ruin a piece. Especially a project that has many curves and crevices like a gun stock. This was the first time I used the mineral color technique. (Forgot I did) First thing was to tape off the hand checkering. Then loaded a spray bottle with “diluted” formula and sprayed the entire Walnut stock inside and out with the formula, and immediately towel dried it. Basically no change in color at this point. The color change takes several hours to occur and the grain is not lifted. Next vigorously rub down the stock with a soft cotton rag to a smooth shine. Then a few coats of satin or matte amber finish.
