My Jetta is getting rusty; would spraying Fluid Film (or Krown, or pick your coating) slow it down appreciably? I'm not thinking of spraying the whole car, just the spots where the rust is popping up. I've got perforation in a couple of spots, and I'm wondering if hitting it with something will slow it down.
Fluid Film on rust?

Nothing short of cutting it out all the way to good metal and welding a patch in is going to stop it or slow it down even for a minute.
The rust is coming from the inside out. A hole the size of a quarter can turn into half a quarter panel or a whole rocker very quickly once you start cutting to find clean metal.

Carwell or Krown or FF will penetrate rust and help to prevent it. But if you have perforations from rust you need to deal with them. Naval Jelly will better in that situation.
I would definitely hit it with something. One thing is for sure, it certainly can't hurt. My folks' car is a 2000 Maxima with a common rear quarter rust problem and I spray it with KROWN every fall and it seems to be slowing the process down greatly.

There are two sides to the coin - the inside out part of it is the major issue - if you cant access all of the rust from all of the places where it may be, how can you stop it? Just slowing surface rust on one side doesnt mean that it is slowing on the other side.
That said, if you can slow it on one side, why not? It may help retain a bit more metal structure a bit longer... FWIW. But FWIW is likely not much, because if it is rotting away from the other side (IF may be an important thing), what does it much matter? Just cosmetic. But nothing wrong with that.
If it was my car, Id definitely dress it with something. Why not? Id also probably try to be proactive with it by making a few small holes and try to get some more into the rust flake and behind the bubbles on the other side of the metal. If there is already minor perforation, a few strategic holes wont do much in a bad way, but will make it easier to keep treatment on it.

Four years ago I purchased a used Escort 2001, these are known to rust at the lower trunk lid lip. This was already happening, very small paint bubbles. I removed the bubbles and applied touch up paint, then sprayed the inside of the lid with Fluid Film. No more rust, it has not spread in 4 years. So does it stop rust, it did in my case. YMMV
Any of the suggestions you can either sand off or clean off with acetone. You need to get behind the rust with Carwell or Fluid Film. From the outside I would dab some naval jelly on the areas after I scrapped the bubbles slightly.

The stuff is top notch. There are people who do rust proofing of vehicles with Fluid Film. I recommend either that or Krown to everyone. It definitely works!
