I painted my calipers with b bque paint and applied high temp decal I found on ebay. Also on ebay I found rotors and pads for my R/T that were drilled and slotted and coated black for $250 for all four
He's not talking about calipers, he's talking about the rotor centers. They get MUCH hotter than the calipers, and the best paint that I've found for them is this. Just use a foam brush, both can be bought at Home Depot, etc. for cheap.
I painted my rotor hats up to the machined surface the pads ride on. Also painted the "vanes" on the outer edge of the rotors.
I used 650* Engine Enamel and it holds up fine.
I can't seem to figure out how to attach pics or I would.
I did the same, hats and vanes. I used the high temp engine enamel in matt black.
Here's a before and after. Took about two hours but I took my time. I rotated my
tires and cleaned my rims at the same time.
Always have to get rid of rust even if you are not painting. Anytime wheels are removed wire brush the surfaces so your wheel makes a good metal to metal contact with the hub lest you risk the lugs getting loose and you lose that wheel.
