I’m looking at dealing with the rust on the Midget. I don’t currently have the money to replace panels, but would like to limit the spread of rust if possible.
There’s a bit of bubbling in a few places but nothing worse than that. How would you guys go about tackling it? I was thinking a knotted wore wheel on the angle grinder, a rust treatment of some description (hydrate 80?) then a quick skim of filler, sand and paint.
Does anyone have any better alternative approaches?

If you have bubbles in the paint that's a sure sign of water ingress to the rear of the paint therefore you have more than just rust / surface rust on the panel - what you will have rust perforation in the panel - unfortunately you are not going to achieve a great deal without cutting out the effected area and welding in fresh steel or replacing the panel - exposing the rust / treating it then filling perforated steel wont prevent the problem reoccurring again I.e. moisture / water can directly access it and when it does it will just swell & bubble again - might look ok for a while but not for long |

I agree.
Post some pics up and those of us who have tackled similar will predict what you will find, but its likely to need new metal.
A wire wheel is probably the last thing you should use even if it isnt perforated, they tend to polish some of the rust, you need something abrasive such as a file sander or abrasive disc in a grinder, or emery by hand if you don't have the tools.
If its come from behind then this is pointless though as holed steel will need to be replaced.

Does anyone have any better alternative approaches? I did exactly the same last year on my wedding car, funds were tight and I caught what i thought was a minor rust bubble walking past. I ground as much out as I could, poured kurust in there, filled and painted just so it didnt look an  in the wedding pics. It's back with a vengeance now, 12 months on. I knew it would be a temp fix though. |

That’s the thing, I’m happy with a temporary fix, but a year is a bit too temporary!
I’ll grab some photos in the morning.

I'm afraid as above there is short term temporary bodge or long term permanent fix.
If you don't mind the short term fix with the unknown life expectancy what I would do is grind it out with a wire wheel and see what you have, put some fibre glass in the hole, then fill it and paint and try and get some rust proofing at the back of it.
The problem with doing this are that you are likely to just store up more work for the future by making things worse, you also need to be careful as any rust proofing behind the panel will be fresh and more flamable which could cause problems if/when a proper repair is undertaken.
Do you have any photos of the rust?
In general my view is that unless it looks really bad and is spoiling your enjoyment of the car then leave well alone until it can be fixed correctly. What tends to happen in these situations is that you go from having good paint with a few rust bubbles in it to no rust bubbles and then badly matching rattle can paint which looks worse.
Just my 2 pence.
