I wrote a post for you, but somehow it disappeared. I've had good luck painting my calipers with special caliper paint that contains a hardener: https://www.amazon.com/gp/product/B004BQ87YK/ref=as_li_tf_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B004BQ87YK&linkCode=as2&tag=thesaabnetwork
This is a brush-on paint, and I initially tried a spray product, but this was better. It levels out nicely. The secret to a good result is complete disassembly of the caliper and good surface prep. I use brake cleaner with a toothbrush. The other secret is not to try to get perfect coverage on the first coat. You'll get brush marks in the paint, as it starts to dry and you continue to dab it. I mask the contact surface of the piston and paint the rest (inside and rim), and I mask the cylinder and paint its rim. Allow 24 hours for drying before applying the next coat or flipping it over. I put the calipers on waxed paper to avoid sticking. Five years later on my Viggen, and the calipers look like they were just freshly painted, when I wash them, that is.
The other thing is to apply a liberal coat of copper-containing grease (the anti-lock stuff) on the clip for the stationary pad, where it plugs into the piston, and I grease the contact surfaces for the back of the pads, where they touch the calipers. You have to be very careful not to get grease on the braking surfaces of the pads, if you do this. I don't get rust problems on my calipers at all.
And finally, failing inspection because there is rust on the non-braking surfaces of the rotors is completely bogus. I can't see how that would affect performance at all.
