I started detailing 4 years ago and learned the basics from Adam's videos. The more cars I did the more I learned. As new tools and products come out I continue to learn new ways of doing things. I do not know what type of vehicle you have but to give you some reference I corrected a 2009 Ram 1500 crew cab (wash, clay, polish, seal) this Spring and that took me 10+ hours. The pickup is not abused. If it was that time would be even higher. It looks like Adam's videos have helped you because you are out trying to get your car looking good. Hang in there and enjoy the process. If you have problems ask the question here on the forums and we will try and help you.
