Based on the many positive responses it must work! I remember trying to salvage some really dried and cracked leather seats. I bought a bottle of black die from a national auto supplier and applied it. I sure didn't get the results like that video. In fact, I had to scrub the hell out of them because they stained clothes for quite some time afterwards. Every time you thought you had it done, you'd pick up another small stain.
