Today I’ll show how I repair the rusty frame of my 1985 Toyota Pickup Truck/Hilux at home in my garage. I’ll also explain why the frames of Toyota Pickup, 4Runner, Tacoma and T100 commonly rust out and how to prevent it.

I havent tried it yet but I've heard good enough reviews of Blaster Surface Shield to buy a gallon of it. I plan to use it on my 1987 4runner after I take care of my own rust issues.
One review video that I appreciated: https://youtu.be/NE1_EiZIVHs
Try fluid film
Did you consider descaler for the inside? On areas that you can reach with it anyway.. also, Eastwood has a great internal frame coating that reviews well.
When you patch a frame you should never do straight up and down welds that makes a very weak point. Any frame built from the 80s up until current they put giant fish mouths and overlap the steel they do not but it up against each other.
