Thanks for the question / tips on the GR 40. It seems after reading on it some more, this is the stuff to get. The question I am going to throw out is what are you guys doing to buff mild scratches on windows out. I am here in the Panhandle of Florida, and we just got our :moon: handed to us by Ivan. I am finnaly up and running again, and I am getting swamped by customers coming in to get thier cars refreshed / or cleaned after putting them thru hell. I have gotten a few that evacuated the area, and when they were on the highway, the bugs were just horrible. Cars come in riddled with bugs all over the front end. It is so bad, you can hardly make out the color of the vehicle. Well, when they pulled over at the gas stations and used thier crappy windshield squeegees, it scratched thier winshield slightly. So what do you guys recommend???
