Aluminum radiator paint?

[PDQ]

For the aluminum radiator peeps, that painted yours black, what did you paint it with? Just high temp engine paint or is there something technically better for this application? Or am I overthinking this.....

Thanks as always

There are radiator paints out there. I usually just use engine paint. Just don’t lay it on thick. The tanks don’t matter but just lightly spray the core just enough to change the colour.
