Car metal primer question

[Mr fixit]

Hi Group,

I know this is a metal forum but I'm not sure of other places to ask my question. Recommendations welcomed.

I have a ongoing, since 2000 (family life stalled it ) car project that I had media blasted 5+ yrs ago and primed with NAPA Crossfire Primer surfacer on bare metal. This was before I read that I should have used a different primer first.

I'm working on the metal repairs now and have read that a Epoxy primer is the way to go.

So the question is, have I shot my self in the foot by using the wrong product, or can I move forward with the correct products that you might suggest to complete the project.
I'm hoping to have it repaired and prepped for paint by the first of the year if all goes as planned.

I look forward to any and all suggestions on what my next moves should be. This will be my first restoration.
