Powdercoating brake calipers...piston diameter?
I have tried almost every coating possible for calipers. Powder coating, caliper spray, auto zone spray, and anodizing. The worst is the auto zone hi temp engine spray. It turned to **** in no time. I then tried powder coating. It did not last and between wheel cleaners and brake fluid it turned to **** as well. Anodizing wasn't what it was promised to me, it cracked but retained color. Caliper spays worked well but in time faded pretty badly but held. The best thing I have used for my calipers has been Testors paint. I don't know why it works well but it does. I have had testors on my calipers for about 10 months now and they look great.
Just my 2 cents. Good luck.

The most durable caliper coating available is the two part lacqur. The spray crap are made for ricers.
Because the curing is a chemical process and irreversable it is highly resistant to all types of solvents and petroleum by products (brake fluid, cleaners etc.). And it is rated to withstand temps up to 800 deg.
I did mine 2 years ago and it is still brilliant and glossy to this day.

Essentially, it's a melted plastic coating, cured at 450F (above the boiling point of any new standard use DOT brake fluid) and holds well beyond that when cured. Powder coat is highly resistant to all solvents and abrasives (try stripping it off sometime). I have my exhaust and turbo heat shields powdercoated and it held up fine to everything except the cat.
Back when I was younger but not as stupid as you, I tried the caliper paints on properly prepped calipers. Sadly it didn't last. The powdercoat I have on there now is perfect, and hasn't been phased on track days where I've had my pads smoking from the heat.

93BlackFD shared some insight in a similar manner but didn't resort to name calling. Whether or not his method is better doesn't matter at this point; I'd listen to him simply because he seems more friendly.

The caliper rebuild kits are only like $30 for the fronts and another $30 for the back. It takes about 20 minutes to take the caliper off the car and rebuild it.

Brake fluid and other solvents will eat through Powder. I've seen it many times. I deal with lots of bikes and cars. On motorcycles, when someone bleeds the brakes, it drips onto the wheel. If the customer doesn't wipe it off completely, they will eventually flake bubble up and flake off. Just make sure whatever you use to clean, wash it off as quickly as possible.
