I just brought a black 2000 BMW 740IL and i was thinking about using zaino zpc to get rid of alot of the swirls on the car. I just ordered a PC so thats what i will be using. What pad should i use to apply to zpc and at what speed. I know that it is going to take me a couple of passes to get most of the swirls out. Also if i follow with Zaino AIO what pad should i use, or should i just apply that by hand? Thanks in advance.
