I recently purchased a 2000 Nissan Pathfinder. The windshield is streaked beyond belief. It's only where the windshield wipers track, but the damage covers that entire area! It's as if the previous owners never changed the wipers. I also believe they used RainX. So does anyone here have any experience with removing/polishing/buffing this type of damage? I talked to a windshield repair shop, and the guy told me to buff it hard with a machine and polishing compound. What do you guys think? Thanks.
