I bought this to remove a scratch in my wife's car. I decided to try it first on a smaller scratch on mine. No luck. I figured maybe I didn't apply enough compound (this is my first time trying it). With a giant gob, again, no luck. After wiping it clean and coming back a few days later, it looks the same. I decided to apply a second coat with a generous helping. Sadly, it still looks the same as before.
