I don't want to dissuade you from fixing it, but the general rule is that touch up paint looks like crap, whether sprayed from a can or painted on in any other way aside from an actual spray gun. There are many reasons, but a lot of them have to do with the way the paint is mixed in an aerosol can.

If you think it looks bad right now, it'll probably look worse when you're done. With aerosol cans, you have no control over the spray pattern, the paint mixture... you have no control of the pressure either. It's a bad scene.

The GOOD thing is, you can get cheap paintjobs from the local MAACO shop. With the original factory color, no less. It might be a few bucks more for metallic paint, but it isn't going to make much of a difference.

If you are enterprising enough to try to fix it yourself, put that effort into masking all the parts of the car that get masked, before the paint gets sprayed on. Strip tbe badges and the trim from the car (or mask the trim and still strip the badges) and everything that doesn't get painted. Then bring the thing to whatever shop you talked to (MAACO is usually cheap) and have them finish the prep and spray the paint on. It's only a few hundred bucks that way (usually). Not bad for a whole paintjob. And the car will look virtually new which is really nice. You can blow $100 and up on a hand wash, wax, and detail. So a few of those would equal your nice new paintjob.

If you're lookign to spend virtually nothing, however, I'd say leave it. The touch up will look worse than the problem area looks totally bare.
