This product is amazing! It really does work! I had an ugly windshield scratch caused by the windshield wipers being operated with no wiper blade on the driver's side. At first I thought I was making the damage worse with the Green pad, but if you just follow the instructions to the letter you will see great results. Once I started the final process of polishing the windshield glass using the White pad with the Cerium Oxide liquid provided, WOW! It's important to take your time, so as not to overheat the glass. Don't apply too much pressure when polishing the windshield or you could warp the glass from the excessive heat. I highly recommend this product.
