I also had deep swirl marks on my black saphire metallic , but a simple polish with heavy grit pad took care of that .i went polished each panel only one time ,if i would had gone over it 2 more times it would had looked as new .i used a orange pad with a chemical guys polish .it is very time consuming to say the very least.
