I got my copy in the mail 3 days ago, and true to form for Airspeed Press publications I had a hard time putting it down. Written in a very easy style, just as the divelight book was, with just enough humor and lots of practical information.
While the emphasis is on drysuits (lets face it, they have more parts, care and problems to deal with) there was quite a bit on wetsuits as well. I would guess that 80% of the book dealt with drysuit specific issues and the remainder with wetsuits.
Mr. Lindblom covered a wide variety of subject, from proper fitting and sizing of an exposure suit to cleaning, care and storage. As well as a section on quick field repairs to get through/on the dive for the day. One whole section was dedicated to glue, adhesive and tapes ... I think the subtitle should have read "more than you've ever thought you needed to know" it was very helpful as I didn't realize there were so many different types of glues and adhesives each with it's own place in exposure suit repair. I was glad to read that "in a pinch DAP" contact cement will work as I had just asked this question here on SB a week ago.
Of course there were also very detailed instructions for replacing seals, zippers and valves of different types and manufacturing variations. The directions appear to be very simple to follow, and 1 seal replacement would easily pay for the book over sending it back to the factory for work.
Aloha and congratulations to Steve Lindblom and Airpseed press on another great book.

If you are contemplating any modifications to your existing suit, or looking at picking up a drysuit I'd say this volume is well worth the price. For wetsuit owners, it's nice, but I would have a hard time putting it in the same category of "essential" as I would for drysuit owners.
