The powdercoating material itself ranges greatly in heat tolerance.
From thepowdercoater.com: "Most powders are manufacturer rated at 250-300 degree operating temperatures."
In comparison, G2 Caliper paint is rated at 980 degrees tolerance.

people, but rather it could
be a problem for some
Exceeding 200 degrees is still a long way from 300 degrees. That's a 50% cushion, not too bad.
I suppose that if I were track the car hard the calipers could reach into the upper threshold of the powder coating temp, but its HIGHYLY unlikely unless I was driving with my foot on the break and probably warping my rotors.
I would think that for my calipers to reach 300 degrees, my rotors would be glowing...
