AB 3 First off, after spending 2 HOURS on one section and becoming exhausted, this couldn’t fix my very light scratches on my cars window.Pretty unimpressive even since I was applying at least 10kg of pressure, working it with a spray bottle of water in a circular motion.For the effort required, I will hire a rotary hand tool and cerium oxide with a pad and rubber spacer. This product MAY work on extremely light scratches but I tried my absolute best to remove the faintest scratches on my car…bummer :(
