The bell of the disc above is annodised aluminium, not painted iron. Do not paint the hub clamping surface else the wheel nuts can keep coming undone.
Also, don't let any paint get on the friction surface, as the paint can burn and damage the pads, and also the brakes will be terrible for the first few miles.
So the only place you can paint is the outer edge of the disc, and the outer edge/sidewall of the bell. You'll need to use VHT paint because the discs reach some crazy temperatures (far higher than the calipers). VHT doesn't adhere greatly, this will be more of a problem if applied in such patches, so it's likely to flake off.
Your best bet isn't to use paint at all, instead get your one-piece all-iron discs plated with zinc/chrome/etc. Or buy discs that are - some one-piece grooved discs are plated against corrosion by the manufacturer.
