I posted some examples of cars I've painted with Duplicolor Mirage paint. It comes in a three can set, with flat black undercoat, color coat, and clear coat. I used to buy it at Checker Auto Parts for $20. I haven't bought any lately so I don't know if they still carry it. I checked and did find it on Amazon for less than $17.
Here's one example, but you need to look at the whole set to see what it really does.
