I have done both on different Rigs.
KB Seal is slightly cheaper then POR 15. Both of those products are very good. Make sure you don't get that crap on your skin as you have to wear it off. Also wear a respirator because those are extremely nasty. I wear throw away outfits when I use those products to keep from wearing the product. Then fluid Film
On another rig, I used strictly rust-oleum and Fluid Film.
I do know that only paint is worthless. Especially on rusted steel.
Great work Sarki. Looks really decent cleaning job..
