Painting bare metal question. How to prep my rockers

[CFMopar]

So I've sanded down my rockers, removed paint and got 99% of the rust off.

There's obviously some pitting and stuff that my scuff pad surface disc couldn't get into to.

I'm going to be priming them next and am going to use https://car-rep.com/product/car-rep-2k-epoxy-primers-400ml-aerosol/ the Car Rep epoxy primer.

But my question is how should I prep the metal? I guess some sort of degreaser first. I was going to use Acetone but people are telling me no. And digging into the specs for that primer is doesn't recommend it. Does anyone have a recommendation? After the degreaser the plan was to use https://www.rustcheck.com/product/rust-converter-2/ this rust convertor.

I've had some say just scuff and spray the primer as it will inhibit the rust. But I feel like it should be treated it first no? What's the process?

Sandblasting. You can get small one for not much money.

Yeah I tried that earlier and it wasn't very effective

You got that pretty darn clean. I would epoxy prime it and then top coat it with something appropriate. I base/cleared mine, very durable, but that is a bit overkill
