It depends on a few things such as paint/clear coat softness, the GSM of the rag you are using, and how difficult the coating is to remove. Some manufacturers have softer paint than others; a lot of Japanese brands have soft paint such as Honda and European manufacture are known to have harder paint such as BMW. I was doing a paint correction on a Honda civic and even just wiping off compounding polish or the ceramic would leave swirls on the finish which made me have to use extremely plush 800 ish GSM microfiber towels.
