Although the plastic world is evolving everyday with new plastics coming on the market everyday the book sticks to basics which makes it in a way time independent. You will however not build a car, a boat or a bathtub with this book. The book handles only about the characteristics of fiberglass, how to handle it, lay it up, how to repair it but stays very superficial on the varieties of objects made from it. It explains quiet well the difference between epoxy resins and polyester resins and when and how to use them. In the exercises there is a lot of repetition however and the book could do with some more explanatory drawings and photographs. For the novice fiberglasser it's an OK book to start with.
