How to keep it from rusting after sanding?

I am going to paint my own car. How do you keep the bare metal from rusting after sanding if you can't get the whole car sanded and primed in a day? I want to take my time with the project and do it at my leasure untill I'm ready to paint it. Then I will make my paint booth and be able to shoot the whole thing without driving my wife out of the house. I have also seen an artical on water based paints. Seems like it would be less toxic but you still have to prime it and clear coat it with regular stuff. Not much advantage I can see. From what I've read here it seems to me the bc/cc system it the way to go. Anyone use Nason paint? I've see some good reviews on it and it is fairly cheep. Is it a bc/cc type paint? Any tips on a paint booth (as in I don't want to blow up the house) or become more brain dead than I already am.
btw I am a newbie and this is a great forum!!!
Thanks, Walt

bare metal needs to be primed as soon as possible, humidity will make it rust, and rust is

one of the best ways ive seen would actualy to be to use a ROLLER to apply a coat of primer to the panel. its something we did a number of times at the dealership, and it worked quite well

most of the times we did it, it was for door dings and other small repairs. but on a few occasions we did entire panels .... but that was only done when spraying wasnt an option due to things like having freshly painted cars in the shop and such

for you, rolling would be a good option. just make sure you dont leave it as is, as soon as its ready for sanding take some sand paper and knock off all the orange peel

then when it comes time to paint either:
A) the panel is ready for base coat
b) the panel can receive a second coat of primer , be re-blocked, then painted

depending on how good your body work was .... just use a quide coat of black paint to find all the lowspots after youve rolled on the primer ....

it takes more time they spraying primer, but doesnt create the cloud of fumes you appear to be trying to avoid

ive used nason paints once .... which is hardly enough to form an opion about them

waterbased paints, never used them so i have no clue

paintbooth .... creat a room in your garage using plastic sheeting and throw some fans under the door blowing into the room, use some good furnace filters to screen out and big stuff, and use a window as the exhaust, again using a filter to trap the big stuff ... wet down the driveway in front of the fans so no big stuff gets blown off the ground, and wet the garage floor also so any paint overspray stays on the floor
