I have hard water spots on my car and they are really starting to aggervate me! I use to buff RV's back in high school but its been a few years since I have used a buffer, I don't want swirl marks and I for sure don't want to burn the paint. What kind of compound/ polisher should I use to get rid of the spots? I have waxed the car twice and they did not go away by doing just that. I would appreciate any help! :beer:
