A book by Dom Colbeck(Dodo Juice Products) John Steele and David McLean and well worth the money if you enjoy detailing your car. Covers almost every aspect of cleaning and polishing your car from basic washing to coatings and cleaning under the car and bonnet. I am fairly new too this game but it is very informative and gave me a basic insight into most of the questions in my mind about cleaning and detailing my car without damaging the paintwork. Also provides information on basic paintwork repair and recovery from scratches and paint chips. A lot of folks spend a lot of time and money on all of the products, this book is a good investment in my opinion and better than YouTube!!!
