Takes the right tools and a bit of skill to trim a windshield without marring it, and to produce a finished edge that looks somewhat professionally done. I trimmed my OEM windscreen shorter so I could look over it. I drew a line using a fine tip permanent marker onto the front side of the windscreen where I wanted it trimmed to. To do this I measured down and recreated the exact same curvature. I then protected the windscreen by using several layers of masking tape... under the marked line, and trimmed the excess windscreen off using a mini bandsaw. I then finish sanded, to the line, using a bench sander, and then dressed and radiused the edges a little by hand using fine sandpaper. The finished result was better than the OEM edge. This is one method... there's likely many ways to do this and achieve a decent result. If you don't have the tools or the skills to do this, personallyI'd recommend you take your windscreen to someone who does.
