For the Gen 2 new satin black powder coat I also discovered that Rustoleum 2X Ultra Cover Paint & Primer "Satin Canyon Black" #249844 is a pretty close match as well.

It leaves a slight sheen when dry but I found that if you take 0000 steel wool and lightly buff in the touch up spot plus a slightly larger area around it (let dry at least 24 hours before doing this), that it knocks the sheen down and matches pretty close.

The good news is most of my touch up needed was on the x-brace below the engine so no one is going to really see it but I wanted to protect it from rusting.
