Thanks mate. I went into a lot of depth because this is the post that I was searching far and wide for when I encountered this problem...

This is definately a job you can do while its on the road (probably more likely in summer) so you can at least neutralise the rust and get the ball rolling.

I'm not sure what you mean about the c pillar - I'm assuming thats drainage for the back window on a sedan/coupe, I'm sorry to hear about that (but i have a panelvan so haven't encountered this prob).... But - in saying that, theres still a lot of problem areas i.e. sills in barn doors and also interior sill above the rear panel windows where the headlining would sit.

Best of luck with your project - its always worth it!
