Epoxy: retreating epoxy on later coat

Occasionally, when doing subsequent coats of epoxy, I'll get an area where the epoxy retreats, and leaves an uncovered dimple, or irregular shape. Got it tonight, coating a paddle. I'd like to figure out why, before beginning another boat.

Tonight, and, I think in the past, I had done some 220 grit sanding, then wiped it down with denatured alcohol. It had sat at least an hour before I applied the epoxy. I'm using Maas slow, in a shop at about 70 degrees.

2nd question. When I had used System 3, the guide was to do subsequent coats within 72 hours, to avoid having to sand. Is that OK for Maas, too?

Thanks
