Lots of people use bilt hamber products to convert and treat rust and I have heard good things.
Personally, I scour out all of the rust so you only have clean bright metal. Any major pitting needs to be cut out and minor stuff can stay providing you remove all rust from the pitted metal.
I always use a zinc rich aerosol primer to cover the bare areas whilst the rest of the repairs are ongoing and that does a good job at protecting the steel.
Be aware that some cheaper zinc primers need to be removed prior to applying your pre-paint primer as they do not adhere well enough and can cause problem later.

I cut out and replace. If its pitted its thin so replace.
Then use an quality Epoxy primer.

When it's thin but not that thin and very local I had metal. Sometimes it gives better results than cutting if it's a small piece. Less risk to déform while soldering.

Bilt Hamber Deox Gel will remove rust and leave just the pits on bright metal. You need to follow the instructions that come with it closely though.
You'll need to decide if what's left is thick enough to just paint over or replace with new metal.
I've had bits of metal that resembled lace once the rust had been removed.
