I was putting the second coat on some fiber cement yesterday (BM 100% acrylic latex) and I could not avoid lap marks. The paint/brush was dragging was I started to smooth out what I had initially applied. Very little, if any problems with first coat with essentially same temperature conditions.
Can I sand these lap marks out and reapply a thin coat with floetrol?
I now almost feel as though I should be using floetrol

Eric,
You answered your own question. Go Floetrol!

I use Flotrol on just about every application.
It actually doesnt cost more money because it adds to the volumn of paint.

Eric, what kind of paint was that? What's the temperature, and are you painting in direct sunlight? Sounds like you're overworking the paint.
Before Floetrol, I'd like to understand why you're getting lap marks.

Well, I solved my own problem and it was a "stupid" mistake that I hope to not ever repeat.
I was using a very good paint, a new Purdy brush and going from right to left because I'm left handed. Unfortunately, even though it was only about 70-75 degrees, the sun had heated up the siding such that it was cooking the paint almost immediately.
Now I'm about to find out how easy it is to lightly sand out lap marks and lightly recoat.
Thanks for everyone's comments.
When we repainted last I tried to avoid painting hot siding, but once or twice it couldn't be avoided. Was rolling with a 6" roller, then backbrushing. I found that keeping a can of water around for the brush was quite helpful -- just "tip off" the brush in the water every few strokes and the paint didn't drag or leave brush marks.
