The only thing I'd change about CP's advice is that if you work in an enclosed area, use a dot of medium to assemble it. For the ribs and other type joints you can walk outside with the whole assembly and shoot the thin where you feel it's needed. The medium will wick like the thin, it just takes a couple extra seconds. As a matter-of-fact, I rarely ever pull out the bottle of thin. A little experience is all you need to develop a "feel" for glueing.
Of course, if you're like the INFAMOUS COMBATPIGG, you love the smell of CA fumes in the morning... (<---for some reason CP you remind me of that guy)
