Some discount automotive places sell compessors damm cheap...Same with spray guns. For this kind of stuff, you dont need a $700 spray gun, heck, I picked up a spare gun for $40 from princess auto, they arnt the best, but they work...I have seen half-decent airbrushes for $20. Its not needed, but its one of these things that once yo get, you'll find all kinds of thing to paint with it).
You should be fine with automotive primer from canadian tire. But if your painting a metal body, make sure you use a metal primer, if your using a plastic body, use a plastic primer. I highly suggest Dupont primers and paints.

If its a high solid primer, a quick run with fine steel wool after it dries helps.

I clean before priming. Usually with pure methel hydrate...and watch your fingers. Human oil is a bitch and can mess with spraying, so handel your parts with gloves.

but thats just me. I spray professionally, so little things that matter to me, you'll prolly never notice. Many get excellent results with plain cheap spray paint.

As Droc said human oil will cause the paint to bubble seen this many time in the autobody shop will be read for paint and some guy touches the primer. Then it bubbles, then you hunt down the guy and linch him. but anyway if you do happed to touch the metal after its prepped i would suggest a good de-greaser don't rub it in too hard, then follow it up with a Tac-rag.
