In very novice opinion, I would consider this very minor rust. Do you think a spray of rust converter is necessary before epoxy primer?

It needs cleaned off, media blast or DA and 180, but it needs to be removed.
You can not paint over rust. Rust convertor or not. Sooner or later its coming back.
 
Yeah, sand the entire thing as fast as you can and then get it in epoxy. What was it cleaned off with? Rough sand blast needs knocked down, profile is too sharp
 
Also -

you will need to wipe Ospho (rust converter) on the bare metal - convert rust, DA and then epoxy.

Not matter how hard you try to sand our rust, it will still stay behind in the micro small pit holes in the metal.
If it is not converted prior to putting epoxy or sealer on the bare metal, you run the risk of issues developing later.

every car that I have restored has had the Ospho process done on it. - ZERO rust issues on cars I did over 20+ years ago.

ALSO
take the lead seams out. There is always rust under them and lead will continue to gas out for a very long time.
Can be repaired and use the bondo with fiberglass in it to repair.
I learned then hard way on this - trust me.

Most definetly. I would use phosphoric acid with 1/3rd water mixed, brush on the area. Then, cover with saran wrap so the phosphoric doesn't evaporate but stays wet dissolving the corrosion. Maybe a day or two covered is all it takes for the rust to go away. Just check under the surface covered to see if it's still wet. If it drys a little just brush on to keep the metal damp. When done, clean the surface with a wet rag and prime. If anything turns black , just take a wire brush or scraper to kick off the black deposits. I've done this method many times and it works well.
