Peeling paint and paintjob

I have a little dodge for a winter car the paint is peeling bad and rust spots are starting to show through the primer.The cars in great shape so I don't want it to rot. I started sanding the rust spots and patch primering them today.The paint peels real bad and water getts under it and it flakes about an inch or two at a time.The hood is missing a 2ft section of paint. Now when I go to paint it do I need to DA it down to the bare metal/primer or should I just get the flaking stuff off and DA the edges of the bad paint and primer and paint over it????If so any quick tips for getting a car down to the primer or metal with out taking 40days of sanding???
Also when I sand the rust down I've been wipeing it clean with Laquer primer and spraying primer on,is there more prep I should be doing???

Monte, when you go to paint it definatly strip it to the bare metal and fix the rust, if it just light surfact rust sand it off prime/seal the car (sealer would be better; do to the salt and winter driving) you can either use a razer blade scraper to strip the car to the first prime then sand that off or get some chemical stripper and do it the easy way after you scrape the big chips off with the scraper. If you have a high powerd air compressor with a needle blower you can use that too to strip the chips off, its kinda fun, but dangerous and messy because chipps fly ever which direction at 30mph! Go get some razor blades, chemical stripper and a case of brew and make a night out of it. After you scrape the paint with a putty knife when using the chem stripper just hose it off, dry it and seal/prime and paint.

DA it down to the primer that is on there and reprime. No need to go to bare metal on the whole car. This was a period of time when all the auto manufacturers went to a different process. GM lost a bundle repainting cars that had the same problem. Also when cleaning or pre-cleaning either use Prep-sol or enamel thinner. Laquer thinner is too hot and will start softening up whatever you are using it on. Especially anything that is plastic.

It would also be a good idea to use Metal-Prep or some other similar metal conditioner on the bare metal to get any rust that might be present in any small pits that you can't see.
If you go to the bare metal you should use an etching primer or a good epoxy primer for adhesion promotion. Then top coat with a good sealer or urethane primer.
