Rust scale removal methods before paint?

I think what you may be looking for is a tannic acid type conversion coating like por15 and many others... one that converts the brown rust to an inactive BLACK magnetite... and seals the surface with a water based latex primer..that you can paint over with enamel once set up.. and dried.. here is a link to one of those products... there are a zillion of them with about the same recipe..

the tractor collector community swears by that class of stuff and it works..
hope this helps

So a self etching primer?

Now I can't decide what to do...lol

This thing doesn't need to be perfect. Etching primer sounds a bit more simple with less room for error than phosphoric acid/primer process. I suppose it might depend on how much rust I'm able to physically remove before hand.

these conversion coatings are a one step deal converter/primer... one of the easiest to get is Rust-Oleum Rust Reformer.... most hardware stores carry it...

Making progress. Still a lot of work to do with a wire wheel.

Good ol' Rust-Oleum...lol Reminds me of something I'd pickup at wally world when I was 12.

Seriously, is it worth using or am I going to be redoing it in a few years, even with a good solid topcoat?

Thanks again Heiti

if you live in winter/salt country you will redo it every few years regardless.. You have gotten it very clean... in your situation I would go with the rust reformer.. give it 24hours in a warm dry place to set and dry then brush 2 good coats of rustoleum black on it.. (or purple or red or... your decision)
then you are good to go...
thanks

Got it done. The wire wheel did OK but I ended up using a flap disk on the heavy rust spots.

One coat of the Rust Reformer. Just a light coat of sandable primer (I like to do a light sanding before paint) and 3 coats of paint.
