Fluid film and wool wax question

We don't like POR-15 here?
I would blast as much loose rust off as you can then do "something" like the Eastwood product mentioned or POR-15, then FF or woolwax on top.
Try to blast out the crossmembers from the inside with a water hose, blow them air dry, then go in with the fluid film on an extension nozzle.
They sell replacement crossmembers for your truck if it gets too bad.
You're on the right track. Doing nothing is the worst you can do.

POR has its place, but an in situ frame coating isn’t one of them.
It requires a LOT of prep and conversion before the final POR coat can be put on. And the POR, while tough, can chip, and can allow moisture under the edges where there is an interface.
Rust encapsulation does the conversion and binding all in one (still should clean, degrease, etc first). Some variants have increased rust protection these days. It has always worked well for me. Costing with lanolin will be even better…. Just a more straightforward coating when doing it on your back under the vehicle…
I've used POR-15 on a couple of vehicles. Religiously followed the prep. Got rid of as much loose rust as possible and used a wire wheel and brush where possible. Used their Cleaner/Degreaser, then their Metal Prep which is a zinc phosphate wash, then two coats of POR-15.
My experience is that it is good, but tends to chip and peel off eventually. If it were for a garaged car, like a hot rod that doesn't see road salt, sand etc I'd say it would be perfect. But for trucks/cars that see daily use and wear and tear...I think the Eastwood Platinum is a better option.
POR-15 is still waaaaaaay better than nothing though. And if top-coated with Woolwax, Fluid-Film or Noxudol it will probably last a long time.
But this truck's frame has seen better days. Anything is better than nothing and will help prolong the life of the vehicle.
If its a car that sees salt its oil based coatings. POR15 is going to be a speed bump for rust.
