This will be short:

Have you ever seen one of those books that looks like it will have a lot of good info on how to do something, open the cover and realize that it's just a "this is nice stuff that you could do if you knew how, but I'm not going to tell you the details of how..." book? This is that book.

To add to that, it's outdated, and even though all the products introduced and shown were of one brand, they didn't even take a picture of them but instead someone drew a picture of the can sitting there...

I agree that this book has serious problems with pictures and photos, because the drawings included are very poor so you cannot identify the difference between the different materials. But in my particular case, people in fiberglass materials stores understood what I was looking for (by the materials and fluids names) and at that moment theory and reality matched perfectly.
The amateur results that I was expecting (car speakers, small boxes) were achieved completely.
