I repainted my TT's calipers as they were peeled and faded when i bought the car. I'm all for a stock look, but like the nickel plating. Make sure to use spray paint. I used the pelican paint and wish it were smoother. It did self level, but not as much as i would have liked. You cant tell unless you are cleaning the caliper or the wheels are off. It is very glossy though.
