My next book is out - a booklet, really. It's on how to make compound-curved interior trim panels for cars. The panels are ideal for kit and home-built cars, major sound system installs, or the complete re-trimming of interiors.
The technique uses sandwich foam panels that you actually develop in situ in the car, allowing the car to act as the mould - and so the panel always fits perfectly.
As far as I know, the technique I use is unique - I've never seen it used by anyone else. It's cheap, the panels are light and provide good sound insulation, and they're easily trimmed in carpet, cloth or leather.
Booklet is in full colour, 24 pages, has 65 pics showing step-by-step processes.
Re-trimming of the rear of a Gen 1 Insight is used as the example throughout the booklet.
What can be achieved (side and rear panels here are both compound-curved, foam sandwich panels):
