Isn’t that what the study I posted, which you dismissed as old, indicated? Paint actually helping with heat dissipation? That study actually tested different coatings and they all had different effect. Even the color of the same paint type had different effect.Caliper heat reduction was measurable with the Goldline coatings vs any other coatings, or even bare calipers.
So perhaps that gold line coating or whatever they market it as, is better than others, I’m not here to argue their claims. But my point is that paint has little to no effect on caliper thermal performance.
It is simply a non issue.
