rust ... how to deal with it

hey guys
ive got an ae82 corolla sedan and its got a bit of rust on it. a few small spots have started to appear over the body work, mainly along the boot lid, rear panel, turret and the front pillars.
i got quoted $1500 to get the boot lid, rear panel, and turret done at the local rust place. this is a bit steep for me and still doesnt cover the other spots of rusts. (its all surface rust at the moment.)
so i am seeking a bit of help, i reckon i could do the prep work myself as in sand back the rust and treat it, and then tape up the areas to be resprayed by the panel beater.
i would like for some info on the best way to treat the rust, and prepare the body for touch ups.
cheers

IMHO sell it or take it to the tip.
It'll only get worse.

If it's only surface rust then rub it back and use some sort of rust eater on it, then get it sparyed like you said. Prep work is alwasy the most expsensive part of panel beating.
With that said, rust is always worse then it looks once you start to work on it...

yeh its all just surface rust at the moment.
so i just need abit of help in the process of removing the rust. does this sound right:
i sand back the rust down to bare metal, then i use a primer of some sort. sand back again and reprime it. then paint.
what sort of sand paper and primer should i be using?
cheers

wherever you take it back to bare metal you should be using etch primer, and dont drive around in primer for weeks, apparently it absorbs moisture and when you get around to painting it, will rust quickly again

are you sure it's just surface rust? I'm not doubting you, just that a few people i've spoken to then actualy seen the car it has not been surface rust. If your definatly going to fix it, (or get it fixed) it cant hurt to pull out the grinder and take it back to metal and have a look. Don't touch rust treatment or convertors, it'll just come back. Make sure you find the cause and fix it too. (leaking windscreen seals, boot seals, etc etc)

Most rust can be fixed. Comes down to how good you are with a welder.

Now, to put in a little prospective. Rust is like cancer. If your lucky, you can cut it out, if your not, learn to live with it. Surface rust is tricky, because it's not bad enough to treat, but it's bad enough to need attention. First off. Is the rust pitted the metal (like tiny little crators in the metal), then there is only 1 choice, CUT IT OUT. With rust, once it's in the car, it's there for good.
The first thing you should do is sand it back and see how bad it is and over how big an area, keep going until no more rust appears, now you maybe in for a shock it could be the whole roof, so be prepared. Don't do it half arsed. Use a sander/polisher or a grinder with a sanding disc. Now don't hold it in one spot, it'll burn and 'oil can'(stretch) the metal, and then your up shit creek. The only way to get 'oil can' out is to shrink the metal. Which is more money as it's not something you can do at home, unless you good with an oxy.
Once you've done that, do yourself a favour, feather the paint edge, in other words smoothe it off, if you don't when you prime and paint it, a big, dirty ring appears.
If it is only surface rust, then rub it back with some wet & dry (used dry) and rub it until it's gone, totally gone, get some prepsol and 2 clean rags, apply the prepsol on with one rag and wipe it off with the other. Once that's done, try not to touch it. Now as cri_ag said, use an etch primer first, then let it dry off, and use your primer, give it good even coats. Don't have it primer for months before you get around to it, or it will be all for nothing, so paint it ASAP.
Some panel shops will not like to work on a job, they haven't done. If they do, you may not get any warrenty for the work, because you did the actual repair. They also will shy away from doing the paint work, on small repairs, as the finish is only as good as the prep work. Some shops won't do it period, they don't do rust. Most will have same answer, "Mate, we will do the rust and paint, but not just the painting". So it'll be down to them doing it all, or none of it.
If the rust has formed and blistered the paint, cut it out and plate it. Do it right the first time and you'll be sweet. Treating it and bogging it, is a cheap and nasty way of dealing with it.
For rust $1500 is not to bad, but it could be cheaper. My advise is to shop around, you'll find that some may not even give you a quote, because it's so hard to give a quote as there is no way of knowing exactly how bad it really is. But that is a rough guide on how to approach it. If you feel you can't do it, then don't, save the $$$ and get a shop to do it.

cheers rob.c
very helpful post 
ive got the day off tomoz so ill go down and have a chat to the panel beater and see what he thinks about just doing the spraying and a few of the hard to reach spots (ie pillars).
the guys im gunna see are a specialist rust place, only do rust repairs, resprays and rust prevention stuff.
ive been to a few other panel beaters around town and they either have to much work, or dont wanna spend the time on it.
so i think the rust place is the way to go, and the last time i was there i had a good chat with the owner and he explained what he would do and what would happen if i took the cheaper way.
ill see how i go tomoz

or does that involve stripping the paint and just respraying it?

from what i understand, you sand back a few cm of the good paint work, and then hen you paint over you smooth it into the existing paint work.

If you use acrylic primer this will happen but if you use 2pac primer then its okay to drive around as it seals and no moisture can get absorbed.

By "even" I assume you mean the same finish (ie. smoothness). Blending is quite hard to do, very hard to get a 100% match. If you get the colour right, cutting it back with 1200 (acrylic) or 2000 grit (2 pac) wet & dry, then using the appropriate cutting compound for the paint type should get it nice.

i cant realy see him using a 2pac primer if he has to ask questions about rust repair, aside that im fairly sure its ilegal to spray it outside, ie. not in a booth.
