My rotors are plated and i don;t drive like a granny.
But my rotors are reflective enough to see my reflection from my driving style of just enough pressure when needed, so i almost never get warped rotors from overheating/cooling.
G2 is a great caliper paint.
I would NOT use it on the hub surface as it will not let the wheel seat properly, i did it so i know.
A thin layer of black spray thermal paint works great on a nwe rotor
