Painting my 83RX (HELP)

Ok here is the deal I started sanding and thaking apart my car today, looks good so far not to mutch rust and only one hole found so far. My question is once I get it all sanded taken apart filled resanded and ready for paint should I prime just the spots that went right to the metal and places that had body work or prime the hole car? The car is wight and will be staying the same colour. I am trying to save time and since im on a pritty tight budget some cash to.

And yes this is my first tome painting a car.

Thanks to all for the help

This site has a good narrative on painting a car. After reading this I decided to do the prep work, removing trim, patching, and rust prep, and let someone else do the rest. Considering a ~$75(minimum)sprayer, air line filters/dryers, sander, and all the consumeables it was going to be $450 + labor to get the job done. I think I will work to get the setup over time, but for now it seems like too much of a job for me.

Hey,
Do yourself a favor and prime the whole car. I paint cars for a living at RPM restorations and work mostly on corvettes. If you decide to undertake this yourself, here's some tips for you, and a small list of supplies

1. HVLP gun. You can get these used online pretty cheap, and they don't wear out.
2. ROBERLO primer, reducer, and hardener. Excellent stuff, easy to apply.
3. Good quality paint, clear coat, hardener, and catalyst
4. A friend who works at an automotive paint supply store. These guys are great and are always happy to help.
5. A BIG roll of plastic sheeting.
6. A compressor with over 1 horsepower at least.
Now here's what to do. Hang the sheeting around all the walls of the booth that you're going to need to make. on one wall, cut a hole the size of a floor fan. Put the fan, blowing side out, and tape up the sheeting around the fan. BE SURE TO COVER THE TOP OF THE BOOTH TOO. this will save you alot of time wet sanding all the crap out of your paint when you're done.
Wet down the floor, just before you're ready to prime, to make sure no dust get's blown up onto your fresh primer. GET A GOOD RESPIRATORY MASK. Not those little dust mask, but a twin cartridge respirator. Perhaps your new friend at the paint store can help. Ask him how to mix the primer too, and remember back to your chemistry classes. Prime the car, and keep the pressure, using a regulator, at about 60 psi. DO NOT ACT LIKE YOU'RE USING A SPRAY CAN. Make passes as wide as your arm will go. overlap your passes, and take your time. After you are done, let your primer dry for about 2 hours. Then, go back and wet sand with about a 12inch block with 600 grit paper. Try not to sand through the primer. Smooth the primer out well. If there are any areas that look wavy, use a black spray can primer and go over the wavy spots. Block sand, and you'll be able to tell which places are low, and need filling. Fill all low spots. Painting is much the same process, but with some differences, too many to list and explain here. Just talk to your new friend and he'll help you out. I hope this helps. Good luck
