Review on Cerium Oxide Grade Polishing Powder by Ben Barrington

Do your research before purchasing as instructions are not included. So buyers should know what they are doing. You need to dilute it to the consistency of a paste (almost toothpaste) and use a spray gun to keep the felt wheel wet and buff the scratch with the edge of the wheel (not the head). takes about 15-20 minutes of constant buffing, cleaning, reapplying and repeating to remove a fairly deep scratch on my passenger's rear window that is 3 inches long. 10 minutes), it will go away completely, but I'm not that picky.
