I have a dark blue 2018 Toyota Tacoma and decided to try and get rid of the swirl marks and fine scratches. First I washed and dried, then applied Meguiars ScratchX by hand. Next I used the Meguiars Ultimate polish and finally a coat of wax, all by hand. I notice in the sun that there are still fine scratches? Why would this be? Maybe I didn`t do it long enough or intense enough?
