Glass Polishing

I have recently learned a fairly expensive lesson I will share with you:  Windshields can be polished but side windows cannot.  The reason being the windshield is a softer two layer safety glass that is not fired as hard as the tempered side windows are, and once you start the polishing process on a side window....It's all over!  (see my post in parts wanted) aritzer38863.3646064815
