DavidB in your PC video you used a wool pad with the PC. Is this okay to use on Clear Coats? I mainly thought foam was the way to go. I have some nagging water spots on my Explorer hood I can't get out. I am wondering if this will do it? I am using Meguiars foam pads (purple & yellow) and their body shop prducts like Dual Action, Swirl Free and Machine Glaze. They work really good but the spots are still there. What do you think? Anyone?
