Thanks for all the replies. I'm sure they will help. What I am talking about are the tiny little marks in the windshield, not divots or cracks. All cars get them, and of course, the more miles (and more aggressive the driver is), the more marks. And to compound the matter, the lower your windshield is to the ground, the more likely to attract little missiles. So no wonder, here's type A me, driving a 17 year old Corvette. No surprise here!
I will work on it soon and post my results.
Thanks.
