So since i (or rather my shop) is redoing the suspension and taking everything off.
I thought now would be a good time to slow down the rust.
I know the gold standard solution is to take off the frame and sand it and repaint it.
The outlay to do this gratly exceeds the value of the vehicle and so it is out of the question.
So I am looking at products like this:
The rubber undercoating choices are also out, since the shop does not want to do that in their workspace and besides they have some significant drawbacks of their own.
I am thinking of maybe Fluid Film .
I know it wont stop rust like the marketing says but slowing it down is perfectly plausible IMHO and entirely sufficient for my application
Anyone here have experience with products like this?

The correct way is to buy a vehicle that hasn't been exposed to road salt and urea.
I'm baffled why anyone in Rustville would buy a local car when it's $1k to ship a car cross-country. With that said, what's done is done.
At any rate, rust never sleeps. Period. It won't go away, and it won't stop. Undercoating simply hides the existing rust and gives it a nice safe place to continue doing its dirty work.
According to my Canadian buddies, FF is the correct answer. It won't stop it, but it will deprive it of oxygen and significantly slow the progression. It should be reapplied annually.

Picking up a couple cans of fluid film tomorrow
PS: The total number of V8 Pathys FS in the US at a given point can be counted on the fingers of one hand and have fingers left over.
Not all of them are 4x4..
Not all of them in w/o major dents or in a good color..
Pretty much narrows it down to one, or maximum two choices, in a given month and everything is a trade off.

If the part's small enough to throw in a tub: evaporust or hydrochloric. Be REALLY care ful with hydrochloric because it'll eat metal as well as rust, just not as fast. Buy Muriatic from a janitorial or construction supply company (or amazon) which is usually extra dilute with thickener so it slops and splashes less. I've seen people throw parts in muriatic for 24 hours, but that seems insane to me. For surface rust you should only need <1hr. Hydrochloric doesn't affect lots of plastics and is less effective at ceramics, so it's GENERALLY safe on those for short periods.

Is there a reason they don't want to just do a quick wire brush and paint for the areas they can get to?
Anyway yeah, fluid film or that CRC stuff seems good to me.
