Next, line up your tennis ball launcher so it's aimed at the glass and fill the launcher with a bunch of rocks of various makes, models, shapes and sizes. Put the launcher on 'medium' or on the middle notch. Fire up the launcher. Wait 10mins.

If your glass comes out without scratches or chips and you can bulk manufacture it for less than the cost of normal 'glass', then i'll buy your windshield. So will every major vehicle manufacturer on the planet. This aint a Nissan problem, it's physics. It's how stuff works on this planet.
