Epoxy ridges from foam brush tipping

Even having carefully tipped the epoxy with a foam brush, you can see, as I began sanding, that it had cured with streaks in it. Maybe a roller would eliminate this? I knocked these down a bit, but since they were in the direction of the flow, I didn't take out the long board again just to sand off all that protection I had just added. On the topsides, the primer had filled those ridges somewhat, and I hoped it would do so again on the bottom panels.
