Unless you're after it to hold a place in your collection, anything you need to know is right here at HT.
Most of the elders here know all the tricks for cleaning, stripping, polishing, touch ups what have you. Keep in mind that some time has passed since it's publication so a few cool things have happened since.
For example, for the collector; the peroxide treatment for body cleaning, reversal of staining and UV damage has to be the grandslam of recent note.
The book itself is printed in black and white and consists mostly of hand sketches and a few B&W photos. By comparison, the archives of HT contain many more expose's, documentations and how tos.
Anything you need to know about the plastic repair portion of the book AND subsequent innovations can be found in my model murdering thread complete WITH color pics.
