As opposed to Jadkar, my version of this DIY is much more stragiht forward.
As opposed to take the caliper off and paint and put 'em in the oven; I just sprayed paint them when everything's on the car.
The brand of spray paint I used is the Dupli color products. You should find it in every automotive stores or even the auto dept. in walmart and Kmart.
here's the link for the annodized red I used.

I'm not sure if that would help but I used the 1200 degree engine paint for a base coat.

Here's the procedure...
1. I'll just get the wire brush thingie with my drill to kind of clean up the brake dust, and also get the paint off the nsx letter..
2. Clean up with paint thinner.
3. Start using masking tape for the part that you don't want the paint getting on, in my case, I make sure there isn't any paint gets on the breeder screws... For the brake rotor, I used the aluminum foil to cover the rotor, and use the masking tape to tape off the gap between the pads and rotor.
4. Don't forget cover the suspensions, and brake hose, I don't think the paint will harm those parts, but it sure looks nicer without the overspray.
5. I also used the plastic wrap and stick them to the edge of the body panels, bumpers and the front lip ( just to avoid over spray, better be safe than sorry... I had once sprayed myself with blue color to my skin for not paying attention where the nozzle pointed at... one of my early spraying days...
)
6. So I went with the aluminum high temp paint for base, then add two coat of the metal cast base coat to give the paint a little depth, finish it off with 2 thin coats of the metal cast red. Note that as soon as the surface is not sticky, it's ready for the second coat. that of course, keep your coats as thin as possible.
7. I ended up touching up the nsx letters with a toothpick (well 3 of them) and the high temp paint I left off...
8. You can see the result in my pic on my post above. Since it's annodized the color is more vibrant under direct sunlight and flashes... in normal darker shade, it had a dark red apperance, I like that cuz it's a little less "Ricey"
