spray gun and air compressor?...
I find many spray guns of different brands with required air consumption: 9-14 CFM, and air pressure: 40-90 PSI, at good prices. But the air compressors I am finding that have the same cfm range and air pressure as the spray guns are costing thousands. And I'm reading many people spending as low as $280 or so for air compressors and its going well for them. Home depot, lowes, sears, harbor freight etc, have the air compressors but are specifications of the spray gun. I dont wanna spend more then a $1000 or so just for an air compressor. Can I still get good results if the air compressor is not in the spec requirements for the gun?

If you don't want to buy a big compressor, buy an LVLP (low volume, low pressure) gun. These guns make more efficient use of air supply. You can also get by using a smaller compressor if you don't over accessorize your gun with things that drain air pressure, such as moisture filters, regulators, and quick disconnects.
Also, look into getting a compressor that is two stage, so it will maintain a more consistent air supply.
If you're only going to use this compressor for a one time paint job, you might want to look into renting one.

I see, one time thing for my beater, I was looking into the two stage and oil free air compressors. Also, I a friend of mine said, if I sand down to bare metal
(i.e. Hood) to put a new primer, and no body filling, I still need to spray on epoxy primer? Cause I thought epoxy primer is only used on bare metal, prior to applying the body filler so that moisture doesn't build up or occur.

Some say etching primer is best for bare metal because it uses an acid to chemically clean and micro-etch the surface to give better mechanical adhesion. This is best if you don't plan on using any fillers after wards, if you have perfect panels.
If you plan on using fillers later, you want to use an epoxy. It can be applied to bare metal or scuffed old paint. Fillers or high build primer can be applied over the epoxy if you need further smoothing/filling. You do NOT want to mix the etching and the epoxy, however. They will not work well together and cause paint lift.

sounds great!, so pretty much a chemical solvent sprayed on prior to using primer when body filler is not needed. So I can use the Duplicolor Self-etching primer then to do the job? Say if the body filler is already on and sanded down and around it is bare metal, can I still spray on the etching primer?

I would stick with epoxy so you have the option of using a finishing putty or filler later if needed. You may get the primer on and decide you want to use a high-build primer to fill in some scratches/imperfections. I say keep your options open, but getting another opinion or two wouldn't hurt, I'm not an expert.
Keep in mind that most body fillers are epoxy, so they work best with epoxy.
