Airbrush repairs?

[EarlyPorsche]

Can I make airbrush paint fixes on my car? Or can I buy a really small gun from harbor freight to make fixes? The paint is Green Granite so its a little metallic which would hide well. The fixes range from pretty small to one area on the rear roof pillar which I would like to totally repaint that is about 3 inches long.

If the repair has an edge or seam that you can paint up to makes it a lot easier, I was never any good at mid panel paint repair, just the color match would be hard then try to get the metallic to match the other. I have used an airbrush for models (solid colors), I am not sure if the metallic would be a problem in such a small gun?

Ok good, the main 2 places that need any fixing have edges on 2 sides and small edges where they blend into bigger panels. Now to figure out what gun to shoot the paint with. I am tempted to just buy the cheapest air brush system or just a tiny spray gun and do the touch ups after I break away the old paint (its a little dry paint problem on these two areas).
