Hi Texarkana,
Not to be rude in any way, but are you sure you haven't ruined your windshield, and made it even worse?
Turning back the clock to 1981, I had taken a weekend vacation out in the country, when I came back, my 1980 Jeep Cherokee Golden Eagle was loaded with bugs.
The Windshield was a mess as well, and was having a hell of a time getting the bugs off, so out came the nice new green Scotchbrite Pad, and voila, bugs all gone lickety split.
Then a 1/2 hour later, went to pull the Jeep out of the garage, hit the bright sun, and it was one big OMG! My Windshield looked like I had cleaned it with 100 grit sandpaper!
It was permanently, and totally destroyed. That was a little $250 mistake, as two days later, I had a new Windshield installed. The only consolation, was I didn't destroy any other Glass. Mark
