As long as you follow the directions precisely, it absolutely does work!
About 12 years ago as you can clearly see I had some minor surface scratches on the hood of my work truck. Thankfully the scratches didn't go beyond the base coat, otherwise the hood would've been a goner.
Me being a skeptical person by nature I decided to give this cloth a try and boy am I glad I did! Here's the after pic, I was truly amazed on well how this product worked!
