I then needed to do my rust treatments and priming before welding in the inner rocker. I really don't want this thing to rust away after putting in all of this work.

I used Ospho rust treatment after wire brushing (I used a brush zip-tied to a metal bar to get inside the cab supports) everything that had surface rust. I then primed using Cobre weld-through primer. I also had to rust treat and prime inside the A-pillar, B-Pillar, and the cab corner. It is amazing how much time it all takes to do it completely.
