The GlassRenu Scratch Removal system is designed to efficiently remove all types of surface damage from glass with depths that have exceeded .025" with NO DISTORTION. There are no maintenance costs and the RenuDisks™ used to grind are inexpensive. The system achieves consistent results using a proprietary dry grind technology and grinding disks that are patent pending. Current operators average 10 square feet with some up to 15 square feet of resurfacing an hour. Our scratch removal systems are currently in place across the U.S., Australia, and Europe. The systems have shown great success in heavy graffiti areas such as Los Angeles, Chicago, Miami area, and Washington D.C. Most companies refer the glass issues to glass shops. As we have seen with current operators, glass restoration, (scratch removal, and other surface damage removal) is very profitable with the right system. The GlassRenu system comes with a 100% distortion free guarantee, it is very simple to learn, and we offer full system and technical support. We have multiple case studies and references available. I encourage you to look into our process and system. Please view the videos on our website (www.glassrenu.com). If you have further questions, feel free to contact me directly at 888.769.0001.
