I have a 2002 Black silverado. I wish I could show you guys some pictures of the damage that my truck has. It looks like water spots all over the windows and paint exept its ruff and looks etched in. I tried useing a porter cable 7424 with a orange pad and a 3m rubbing compound then wolf gang total swirl remover. It just made the paint shiny and the spots less notice able. When the sun hits it just right now i have all kinds of hologram marks and you can still see the water marks. I trieded Nu Glass from napa on my windows and it would only remove the spots if i srubbing really hard which left scratch marks on my glass. Anyone have any suggestions?
