Foreword

Since 1914 the Vehicle Builders and Repairers Association has been intimately involved in the history

and development of the motor vehicle and repair techniques. The onward march of technical progress

increases each year with vehicles becoming more complex and where the ancillary equipment, especially

the electrics, require delicate handling and treatment as part of the repair process.

It has never been more necessary to encourage young people into the industry, to equip them with the

necessary technical skills and tools plus an ability to work quickly, confidently and efficiently to maximize

profit whilst safeguarding their own and their colleagues’ health and safety.

Vehicle Body repair is both art and science. Repair of Vehicle Bodies addresses both sides of that equation.

Qualified technicians able and willing to apply themselves diligently and accurately to their task are a

scarce resource, commanding increasing respect and greater recognition than ever before.

Everyone has to begin somewhere. This book is an excellent starting point providing the basic essentials

as well as the more advanced skills and knowledge needed to equip students for a successful career in the

body repair industry.

Like all businesses, body repairers rely heavily on their most valuable asset, their staff, for survival

and success in their specialist field. Pride in the job is still very much in evidence but it is essential that

everyone involved in the repair process performs efficiently and consistently. This book underpins this

process and goes on to become a significant source of reference for the future.

Preface

This book is written for a wide range of students and professional practitioners in the field of vehicle

body repair and re-finishing. It is a text book and reference work which covers the concepts, principles

and skills needed to carry out effective vehicle body repair and re-finishing.

It will be useful for the professional practitioner whether working on current models or restoring vintage

or classic cars. The DIY enthusiast will find it easy to read and useful as a work-shop manual when

carrying out tasks, or projects, related to the vehicle body.

Students who are studying for NVQ, SNVQ, National Diploma, Higher National Diploma or Foundation

Degree qualifications in motor vehicle engineering will find the book an ideal text and reference book for

both the practical skills and the examinable content of those courses.

For NVQ/SNVQ students, Tables P1 and P2 will help in portfolio planning. Table P1 shows the

qualification framework for Vehicle and Body Paint Operations Units from Automotive Skills Limited.

Table P2 links the qualification framework with the contents of the book, showing which sections in the

book relate to specific units. This table will help guide readers who are using the book as a course text or

reference, with links to the underpinning knowledge and skills as well as to the material included in the

NVQ assessment.

The book deals with the craft techniques needed for working with ferrous, non-ferrous metals and

composite materials as well as with materials joining technologies and the use of body- and re-finishing

shop equipment and tools. It is written to be as comprehensive as possible. I hope that the reader will

enjoy it. If you have comments on this book, mail me at
