I am an experienced armor modeler but I am always looking for new painting and weathering techniques. I found this book to offer several color schemes and painting approaches for the Sherman tank. I have been able to take and adapt the author's ideas to my work on some recent models. My litmus test for modeling books is simple: whether it helps me improve my skills in the hobby or not. This book did.
I do not have the time or patience for scratch building using styrene plastic and I seldom use aftermarket parts on my models--in part because I have a hard time making large cuts on a $40 plus tank model that I may or may not be able to repair. The author provided information about upgrading Sherman tank models with aftermarket parts and scratchbuilding parts. That is not, as stated, my interest, albeit it may be interesting or valuable to another modeler with different skills.
I have three other books of the same genre by the same author; I have ordered another. My opinion is that these are good products for the serious modeler and worth the money.
