Just to be clear I was not making fun of the book but rather the statement. I too have seen the book and it is a great book. I also agree that this is a far better approach to a diy project than asking for advice at the local big box store. Went to orange one the other day and asked for the best exterior primer they had. Guy tells me how great this stuff is and how happy I'll be with it. "And I can use it for exterior" ?. "Absolutely". Quote from label " For interior use only" !!! Over to elec dept. Looking for Sq D QO arc fault 15 amp breaker. They have 20 amp only because nobody uses 15 amp. I proceed to tell him that 99.9% of bedroom circuits around here are 15 amp, much to his surprise. "Well you don't need them anyway they did away with that code"!
