Duragloss nu-glass is a blend of cleaners and selected abrasives formulated to remove water spots from glass surfaces without scratching. Duragloss nu-glass can be applied by hand or mechanical buffer. Many drivers are afraid to polish their vehicle's windshields for fear of scratching it. Duragloss nu-glass is a safe way to polish glass without scratching, distorting or damaging the glass. This gentle cleaner removes what is on the glass without harming the glass itself. Before your reach for steel wool or some harsh solvent, try Duragloss nu-glass. It safely removes water spots, tree sap, bugs and stubborn road film using a combination of cleaners and abrasives. The abrasives smooth the outermost glass by polishing away rough water spots and dislodging stubborn bugs and sap. The cleaners remove films and dirt that cloud your visibility. Even if you've never polished glass before, you'll see a huge improvement in smoothness and clarity after using Duragloss nu-glass. Duragloss nu-glass contains lubricants to protect the glass from abrasion. Apply it by hand or with a buffer to easily remove imperfections and improve the clarity of automotive glass. If you don't have a buffer, a great alternative is the spot buffs kit, which includes 4 inch pads and a backing plate for use on an electric drill, not included. Use the white polishing pad on glass. It enhances the smoothing ability of the polish but it will not scratch the glass. If applying by hand, use a polyfoam applicator. Once you've polished your vehicle's glass, use Duragloss rain repel, not included, to seal and protect the glass. Remove water spots, tree sap, bugs and road film without scratching; Duragloss nu-glass is a safe, practical glass polish that really works.
