my wife has a black cts,and it has many swirlmarks and small surface scratches.if i do a complete zaino job on it,will the swirlmarks and scratches be less noticeable?i am looking for input from guys w/black cars.thanks for ypur input

 

Zaino recently came out with a swirl remover which will help you more then Z5. I bought some but haven't used it yet! AFter that you may want to do 2 coats of Z5 the a coat of Z2.

In addition, you may wanna find out what is causing the swirl marks? Auto car wash? Wash Mitt? Drying towels? Etc. If you put the effort in to remove swirls, I would start off with new wash mitts and drying towels/leaf blower to minimize swirls in the future.
