A tech article in the on-line SCOF library explains this process. If you are a SCOF member review the article "Replacing the Glass in the Windscreens of the Newer Style Cars." Email me if you have trouble locating it
Another article on that same tech library page titled "Glass replacement - new style with bow (.pdf)" has a number of color pictures and more detail on the repair process (requires Adobe Acrobat free reader to view it).
