First of all my car is black.I have tried clay,polish,and vineger.No Luck.When you look at the paint from a normal view u cant see water spots,but when i take it out in the sun well the all appear.I have etched in waterspots here and there and a couple of etched in bird droppings. so i want to use something that will take car of all of that.I have a porter cable d.a polisher and im thinking of using a wool pad and 3m's finesse-it. What can i use?
