Rod and Custom.... I have to try some of that out. Our truck has water spots on the windows (easy to see with the really dark tint) and I have tried tons of stuff and none seem to work. What about getting scratches out of windows, is there any way to do that because one chemical my dad used took off the soft stuff under the rubber around the windows and one day we rolled them down and it scratched lines all the way down them.... Any suggestions would be appreciated, thanks.
