Welcome! I really like those CTSV's. The videos are a great reference just follow them and you will be ok. Like Chris05GTO said you will need to use a machine to correct the scratches/swirls you have. I use a Porter Cable but the Flex or Cyclo are great as well. I have found that good technique in washing, drying, polishing, waxing, etc. is key in keeping scratches to a minimum.
