I know the only way to entirely stop it is to cut it out and replace with new metal but not wanting to go to them extremes, want to sand it back to bare metal and kill the rust with some rust killer stuff and then skim it up paint it etc, what's the best stuff to use that actually stops the rust in its tracks?

I wire brushed all the scabby/rusty parts down to bare metal on the underside of mine and then used this.

It can either be left alone of painted over. I then painted over mine the same colour as the car 
Mastic 121
Stone chip
Paint and lacquer.

I used that and rust came back. Think my efforts might of been a bit slack as had loads of stuff to do. Use it up as it doesn't keep very well. I bought the grey and the black as us easier to tell which bits have had a second coat.

Is this the immaculate Sierra?
Just spray over it, stick some polish on it and then move it on.

That's the same mentality young men in magaluf have about girls.

No not Sierra didn't get that in the end other chap backed out of the deal so still got the Passat.
Its for BMW e46 rear quater panel on the edge where it meets the bumper, all that stuff above looks as if its meant to be put on and left on? I want to treat the the area where its corroded and then repair and paint the quarter panel so need something that kills the rust and then disappears if that makes sense

You can't kill rust. It'll always be there, waiting to infect the metal again, like a parasite.
