use polish for swirl remover, use very soft cloth, when i polish my car, i usually pour polish on a soft and clean cloth and just tap it on few spots and then i just spread it around with the cloth to cover all the area and then i just used my bare hand to remove the heavy polish, by rubbing it, this way i know i can go hard on the paint without any worries of scratching also this way i know which area is smooth and which 1 is in it. also i tried on my friend acura 3.2TL, he had few scratches i used soft cloth and pour some gasoline on it, and it literally removed all the scratches, and if you dont want any more swirl marks on the car just do touchless car wash, i always rinse the car first, pour some soap around it, then high pressure rinse, and then wax and i am done ...
