I do not believe such a paint exists but depending on your car you might able to buy a set . They would also last a lot longer .
Auto zone sells a chrome paint not sure on temp but doesn't give the shine like chrome does. Next bet if you can't go he chrome route would be a nice engine paint seen a lot of colored calipers that look nice through the rim spokes.
Keep in mind your calipers are made from aluminum for a very simple reason. It is just like the alternator which is also made from aluminum. Yes, they are cheap to make but also aluminum disperses heat the fastest than any other metal.
Heat is the one thing you do not want in your calipers. Once brake fluid gets to a certain point, it will start to boil & once it boils it turns into a gas. Now since gas can be compressed easier than the brake fluid, it also means your pedal will go to the floor.
That is why if you ever been to Pike's Peak or other very high mountains that they have those brake checking stations. To keep your brakes from overheating & causing the fluid to start boiling. Now when you paint a caliper, you now have screwed up that dispersal of heat effectively causing that caliper to now get hotter than it was designed to do which during normal braking around town or stop & go traffic may cause those brakes to fail since you have now raised the temperature of the calipers by applying a paint to those calipers.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
