Next time before you kill the model, let the superglue set for a couple of hours, go have some refreshments and come back. Start sanding the glue with some 600, 800,1000, and so on until you hit it with some 2000. Get some bluemagic, (wheel polishing cream, the one thats blue colored) and start polishing, then hit it with Your best car polish and You got Yourself a new windshield. Worked for me.
