This is a good thread to add this in - For those with older cars, it makes a huge difference to buff out your glass every year or so. Everyone knows what the view is like after a new windshield
You can have that view again. Take out those small acid rain and sand pits, water spots. Easy DIY and very inexpensive (if you have a high speed buffer). This is a good surface to learn about high speed buffing - rather than your paint.
