1. Powdercoated aluminum has a resistance up to 500 degrees. Ceramic enamel is good up to 900.
2. Decals are applied after the 3 coats of color, and then are coated again with 3 more coats. Each coat being able to with handle 900 degrees.
Paint chipping has to do with prep work. Prep is everything when dealing with paint.

VHT(R) Brake, Caliper. Drum & Rotor Coatings have been specifically designed for the custom detailing of brake components. It is heat resistant to 900 Deg. F (482 Deg. C) and will not chip, crack, fade or rust even under extremes of operation or road and weather conditions.
There's a reason no production car, at least high end car, comes installed with caliper covers.
