I am needing to fiberglass a spot to repair it and need some advice. I am planning on using bondo fiberglass resin but should I apply it before or after the epoxy primer.

Agreed. I don't know what you are repairing but if you are using fiberglass or body filler for anything other than smoothing over low spots, it's not a matter of if it will come back out but when it will.

With any filler material you need a mechanical bond. 80 grit scratches work well. If it's a hole of any size you need to back it up with something( screen, foil, etc)that is attached securely to a stable surface.
