Rustolium Satin Black works well with a good prep. Comes out close to the Hot Rod Flatz color. Takes about $60 to do two good coats on an average car. Looks great for 6 months, okay for another 3. At the one year point it starts to show some grey. Hit it once a year and it will look decent.
Great for cars you beat on. I'd rather spend money on go fast parts.
