2nd that. I used this series to undertake my own stainless repair. Its easier than I imagined. The real learning curve for me was learning less is more and to take my time. I had a spare set so had nothing to lose and now I'm fixing both!
My tip, pay attention to how light he's hitting. Its VERY light. It takes almost no force. The other thing is at first I thought he was just hitting it too much. But I learned quickly that creating a tight pattern of hits with no gaps, made for a smoother surface on the shiny side.
