Spray painting them with Hammerite will give you a better finish than painting with a brush as I found to my cost :thumbsdown:

I have used Smooth Hammerite for years, works well. I was a powder coater in my past life & you would need to remove all the seals & strip them. The biggest problem would be the masking,powder goes everywhare. Also depending on colour the heat will affect the colour. Hope this helps. 
For the Yanks on this side of the pond who can't get Hammerite, caliper paint will work or try my favorite, a zinc primer. Griot's used to have the zinc spray, now I get it from Wurth (a wonderful web site). Over here we call that part of the rotor "the hat" as in " I think I'll be like all the other tossers and paint my rotor hats". The zinc spray has a hard finish, heat does not effect it (it is recommended as a primer when repainting wheels) and I think it offers an attractive, contrasting color behind the wheels. Especially if you use a different color for the calipers. From the pictures, the zinc appears to be the same color as the Hammerite - a flat, light grey. Who knows, maybe it is the same stuff.
I use a wire brush (one of those wire tooth brushes that I imagine Jaws would use in a James Bond movie. I think Griots still sells them) and brake cleaner to make sure the surface to be painted on the rotor hat is clean. I do not mask off any parts of the rotor hat. I hold a piece of cardboard up by the caliper to protect it from over spray. I spray the hat without getting too much on the vertical surface that mates with the wheel. As for overspray on the rotor itself, I wouldn't get to fussy - you'll wipe that off the first four feet you drive the car.
When I swap out the snow tires/wheels for the summer shoes, if the rotor hats need some freshening, I clean them with a shot of brake cleaner (the zinc spray stands up to it) and re-spray.
