I just tried the Auto Glym glass polish on my wife's beater. (93 accord). This stuff is amazing!!! It completely removed the rain spots from the front and rear windows; and that freaking sea mist from the ocean that I can never fully remove from normal cleaning! :shocked I must truely say that the windows look newer than the car. After reading on CMA's site about the glass kit I thought why not and give it a try. I'm now glad that I did try it. Plus with the help of a pc7424 it was a breeze...
