I wield the brush as lightly as possible in rubber-gloved hand. The first coat is thick, too thick. The second coat is semi-gloss — ah, much smoother — and shinier, too.
And it was the semi-gloss that I used yesterday to do the touch-ups. Which is, I have to say, my favorite part of the endeavor: inspecting, looking at the whole, spotting the little places that can be improved, and ... improving them.
Maybe it's satisfying because it's a chance so seldom afforded us in life — this ability to go back and tweak ever-so-slightly the choices we made — just enough to make a difference.
