I like Valspar Tractor and Implement gloss black. Sure looks black to me. Tractor Supply used to carry it but then changed to their own brand (probably to save costs). I have found it on Amazon (6 cans at a time).
I like Duplicolor gloss black engine paint with ceramic
It goes on great , holds up well. The next best to using mixed paint and a gun
Available at the common auto parts stores like advance.. Etc
