Specifications: Due to chemical and physical reactions, cerium oxide is the best polishing powder for glass removal. Practical DIY repair glass kit has multiple polishing tools, completely for you. It can restore lightly scratched windows, mirrors, tabletops, windshields, glass tables, fish tanks, etc. These tools are great to eliminate scratches on the glass, very practical. Supplies needed: 1 cerium oxide 2 water (distilled water is recommended) 3 polishing 4 electric drill 5 small plastic basin (pint or quart size) 6 bottles of spray Instructions for use: 1. Thoroughly clean the area you want to repair. Make sure that there is no dust or dirt on the glass, as this may cause other scratches once polishing begins. 2. We prepare two small plastic basins. Containers of quarts or pints work well. Add half of the water. 3. Put the polishing wheel in the water; let it soak completely, but dont drip. 4. Put some cerium oxide in an empty bathtub, and add enough water to form a mixture (thin paste mixture). 5. Put the buffered polishing wheel on the electric drill, and then immerse it in the cement slurry. 6. Place the polishing wheel in your work area. If the scraper is near the corner of the window, use a small-sized felt wheel to make the movable wheel move up and down in a circular motion. Make sure that the grout does not dry out, as this may cause the glass to overheat and crack. If your mud is drying, you can spray it with a spray bottle filled with water.
