Hi gang. Here's the winning steps.

If you have the car in bare steel, epoxy prime ASAP. Body work over that. Then primer/surfacer. Next would be Sealer and color. That last step is a same day process. Sealer has a short recoat window. So, don't seal if you are not going to color.

As for etch prime, this is a process if while doing the body work, you cut through to bare steel. Use a little etch, prior to primer/surfacer. Most primer surfacers don't very good hold out (metal protection). I hope this helps.
