I am new to the buffing world. I used the three steps of green, orange, white polish with my new flex machine, which I love by the way. After putting on a coat of carnauba. When I tried to remove it, a fair amount of down pressure was needed. I used a double soft towl, brand new, but saw a few small scratches were I had to use pressure. I went over the area again with the white polish, and seems to make them go away. Should I be using the sealer? Was the day to humid? (it was humid, here in Md.) Any help would be appreciated.
