When you are ready to strip it, I prefer aircraft stripper. Spray on, let sit for 30 minutes and scrape off like butter with a plastic putty knife. All the way to metal. Lay down plastic under the area b/c it makes a mess. Don't get it on you either b/c it burns like hell. Afterwards I use a D/A sander and scuff the metal up with 180-220. If the metal is really bad I work my way from 80 gritt but it takes forever.
If you can, do one panel on a time since the car is in your driveway. Do the repairs and then prime the panel in etching primer and/or with epoxy primer. After all the panels are done, sand the car down and spray another coat or two of epoxy primer and then your ready for paint. Of course all this would depend on your DIY skills. The most important part of a paintjob is prepping IMO. You must be diligent with sanding and masking prior to final spray. When you think the car has been sanded enough for final coat it means you still need to spend another 4-6 hours minimum sanding
If you don't have much experience with cars, you may do what many in your position do and try doing too much work too fast. The cars usually end up as Yard ornaments. Patience is key with painting.
I have been doing paint as a hobby for about 5-6 years but am not an expert. I have been talking with a few local pro's for years and have used their advice to hone my skills. There are others on here that do paint as a career I believe and will most likely chime in.
Please tell us a bit more about your experience with cars and your budget. It would also be great if you let us know what kind of tools you have access to. That will help members give you the best advice for your skills, budget, etc.
