I started on a guys dark blue Ferrari today and have a couple questions. The paint appears to have no swirls or scratches in it. I thought I would clay it and then use PB professional polish by hand. If it needs more than that I have the pc to use. I just don't know how hard the clear is on the vehicle. I ordered some Nattys Blue specifically for this car. It won't be in till late this week. I have Collinite 845 and 476. I also have DG 601 and 105. What would you folks recommend? I also need to know what to use to clean the cloth top and protect it. Thanks for any suggestions.
