Decals
High temp paint for the rotors. The hardest part about decals is lining them up. Also make sure to clean the area good and use ammonia free cleaner to do it. Also once there on use a credit card or your license to smooth out the bigger air bubbles. The really small ones will come out on there own in a few days.
I just realized i said rotors in my first post, I meant calipers like you said. There not that hard to put on, just make sure your not in a hurry take plenty of time. I spent 15minutes aligning the decal I put on my laptop, but it is perfect.
