I don’t know anyone who has paid for that book. Moldtech makes money when you ship them your tool for texturing. I guess the Chinese equivalent has the same setup. It seams to me that moldtech keeps there technique as top secret. FYI: I believe it involves acid and base slurry that base bubbles in a consistent size allowing the acid to penetrate and etch the steel. The base restricts the etching process and walla. Genuine Imitation leather. Can someone back me up here? I am guessing.
