I have tried a bunch of paints over the years and have found this to work best. It's more likely because it has Ceramic in it which makes it harder and holds up better to rock chips on the wheel well mouldings better.
Here is the info:
Dupli-color
(Low gloss black) - DE-1634 <- says this on the cap!
On the can it says, Engine Enamel with Ceramic.
This is a near perfect match to the original color and its stronger. All the trim on my white T-Type is done with this paint.
