Removing Swirls and Fine Scratches (VIDEOS)

I have been trying to take the time to write this post but unfortunately my full time and the detailing I do on the side are not leaving me with much spare time. I have taken some videos of 50/50 paint correction that I'd like to share with you all. All the videos below are taken by applying a painter's tape to divide the panel I'm working on into 2 panels. After that, I go ahead and work on either side of the tape and leave the other side untouched. When I'm finally done I simply remove the tape, turn on the flash and then I start filming.
