I am using my cars over the winter and they get covered in road salt. The cars are showing signs of starting to rust in the wheel arches. How can i stop this or at least slow the progress of rust? I painted the arches of the car in POR-15 in the summer, but it has not stopped the rust progressing.
I want to slow the pace until i can save and find a good bodyshop to cut it out, replace metal and repaint.

Not an easy task unfortunately.
I guess the easy solution would be to just wash it and waxoil it. I've done that to plenty of cars. The worse thing is getting the wax off again when its resto time..
If you want to go to the next level I'd probably pressure wash, wire brush best I could, spray with phosphoric acid a few times, zinc prime and then probably raptor followed by waxoil. Hardly a cheap or quick solution but theres no point in painting over rust without neutralising it and no point in neutralising it without sealing it somehow.
Avoid por15

Depends what the rust is, if it's just surface rust, I clean it up best I can, treat with a converter (my current favourite is Cortanin F) then coat with a underbody wax (Bilt Hamber dynax UB in my case), this seems to be working on few spots on my daughters KA.
If it's coming through from the other side there is not much you can do unless you can get to both sides and clean it back to something close to clean metal, cleaning up what you can and coating with something similar to the dynax UB might help stopping it spreading though

And I won't sit down. And I won't shut up. And most of all I will not grow up.

Just clart it over with copious amounts of the thickest grease you can find. If air and water can’t get to it, it can’t rust.

I did that once and the grease mixed and emulsified with the water, it was a tin of something the previous owner had left in a lock up though, seem to remember it was something weird used on railways when I looked it up.
